Noteworthy rainfall across New York State this past weekend

Two major systems brought significant amounts of rain to all of New York State this past weekend. Tropical Storm Fay moved up the Hudson River Valley while a large front from the West hit western and central NY Saturday and Sunday.

7-day rainfall totals for New York State as of 12 July 2020.

Most counties and townships received a minimum half inch of rain across the state, which was timely given the fact that most of NY had transitioned to abnormally dry conditions, or moderate to severe drought in some areas, as of 10 July. Click here for additional drought status information.

More than 3 inches of rain were recorded in Catteraugus, Lewis, Madison, Oneida, Onondaga, Orange, Oswego, Rockland, Sullivan, and Westchester Counties as well as all boroughs of New York City. Smaller areas of Livingston, Monroe, Ontario, Seneca, and Yates Counties also received similar amounts.

Lumberland and Highland Townships in the southwest corner of Sullivan County may have experienced rainfall in excess of 8 inches.

5th Annual Invasive Species Mapping Challenge

iMapInvasives has put out a call for help and we’re happy to do our bit. Check out this citizen science project looking at increasing the amount of information regarding invasive species throughout New York. Written by Mitchell O’Neill, End User Support Specialist for iMapInvasives.

There is one more weekend in the 5th Annual Invasive Species Mapping Challenge – ending Wednesday July 15th! Join this citizen science effort to fill data gaps for four key invasive species in New York State’s official invasive species database, iMapInvasives. The species are jumping worm, tree-of-heaven, water chestnut, and European frogbit – which have wide-ranging impacts on land and water resources, agriculture, gardening, and recreation.

In this webinar, the iMapInvasive’s team cover the identification of these species and how you can participate.

 

Did we mention there are prizes for each species? Here is one example.

Great data has come in over the past 2 weeks, but it’s still very much anyone’s challenge! The top contributor for each of the four species wins a prize!

I encourage you to go out and search for invasives this weekend – remember to record not-detected records if you search for one of the species in its habitat but did not find it. View our webinar on identifying these species and reporting them to iMapInvasives here. Please email imapinvasives@dec.ny.gov with any questions!

Pollinator Friendly… Lawns?

“The dandelions and buttercups gild all the lawn: the drowsy bee stumbles among the clover tops, and summer sweetens all to me.” –  James Russell Lowell

Dandelions, clover, and many other lawn weeds can help sustain pollinators.

It’s Pollinator Week, a week dedicated to halting and reversing the decline in pollinator populations and recognizing the valuable service they provide.

There are plenty of resources out there to create pollinator gardens and meadows. NYSIPM biocontrol specialist Amara Dunn has been documented an ongoing project trying to create habitat for pollinators and other beneficial insects to help support agricultural systems in her blog, Biocontrol Bytes. Head over and check out her efforts.

But what about places that can’t allow tall vegetation because of space, inability to weed areas, or aesthetics? Lindsey Christiansen, CCE Albany and I decided to explore the recommendation to create pollinator friendly lawns.

Many recommendations prompt us to allow spontaneous lawn flowers (weeds have attained a PR manager) to flourish. A Massachusetts study found 63 plant species in untreated lawns. In a parallel study looking at mowing and pollinators, they found that lazy lawn mowing led to more spontaneous lawn flowers leading to more pollinators.

But Lindsey and I were wondering if there was a more formal way to create a pollinator friendly lawn. We searched out and found a number of seed mixes and a project was born.

“The best laid plans of mice and men…” – Robert Burns

While fall is a great time to put down seed, we solidified our plans in October, leaving us with little time. We decided to spend the remainder of autumn prepping the plots and wait until winter to put the seed down through dormant overseeding. We laid out three rows of 100 sq.ft. plots. The first row was scalped by running the CCE lawn tractor over it at its lowest height of cut. The second row was stripped using a sod cutter, and the third row was aerified multiple times using a core aerifier to break up the soil and create open soil.

Three rows of five plots are shown against a satellite view of CCE Albany. The first row was scalped, the second was cut with a sod cutter, and the third was aerified.

The demonstration project was established in an unused part of the CCE Albany property which allows for road visibility.

Two rows were prepped using a sod cutter and aerifier rented from a local hardware store.

Removing sod cut with a sod cutter is much easier when you have good turf. The weedy lawn proved a challenge to remove.

 

Synchronized seeding

And then it was time to wait. Ideally, we would have a stretch of bare ground in March with a few inches of snow in the forecast. So we waited. And waited some more. But it was a winter that wasn’t and as the forecast showed above average temperatures into the future, we decided to scatter the seed on March 6 with hopes that winter would provide a last gasp.

This table lists the seed mixes used in the study and what species are listed. MN Native Landscape Bee Lawn Mix includes Sheep Fescue, Hard Fescue, Chewings Fescue, Creeping Red Fescue Dutch White Clover, Creeping Thyme, Self-Heal; PT 705 Xeriscape Lawn Alternative includes Banfield Perennial Ryegrass, Eureka II Hard Fescue, Quatro Tetraploid Sheep Fescue White Yarrow, Dutch White Clover, Strawberry Clover, Sweet Alyssum; PT 755 Fleur de Lawn includes Banfield Perennial Ryegrass, Eureka II Hard Fescue, Quatro Tetraploid Sheep Fescue White Yarrow, White Clover, Baby Blue Eyes, Sweet Alyssum, Strawberry Clover, English Daisy; American Meadows Alternative Lawn Wildflower Seed Mix includes Sheep Fescue Roman Chamomile, English Daisy, Yellow Daisy, Creeping Daisy, Dwarf California Poppy, Sweet Alyssum, Five Spot, Baby Blue Eyes, Soapwort, Creeping Thyme, Strawberry Clover, Johnny Jump-Up; and Agway Conservation Green includes Perennial ryegrasses, Red Fescue, Kentucky Bluegrass White Clover

Five seed mixes were chosen for the demonstration project. For dormant overseeding, it is recommended that you double the rate, but we were sometimes restricted by the amount of seed we could purchase within our budget.

Snow cover on the dormant overseeded plots.

Winter finally threw us a bone on March 24th. The theory behind dormant overseeding is the weight of the snow pushes the seed close to the soil and as it melts into the soil, it draws the seed down with it through capillary action. The snow also protects the seed from predation. We can only guess how much seed to we lost to birds over those weeks.

And then it was time to wait again. And we were waiting in our homes due to the shutdown. So it was exciting to visit the site in early June and find baby blue eyes, dwarf California poppy, and sweet alyssum in bloom. The plot we were most worried about due to the small rate of application had the most visual pop.

The sod cut plot seeded with Alternative Lawn Wildflower Seed Mix was the most dramatic despite having the lightest rate of application.

And there were pollinators!

Lindsey Christiansen is pinning a clear plastic sheet down over existing lawn.

Solarization is an IPM technique using the sun to create high temperatures to kill existing vegetation.

We also started a fourth row, this time using solarization to prep the site. Plastic sheeting heats up the soil, killing existing plants and the seedlings of any weed seeds that germinate over the summer. We will keep the sheeting in place until it’s time to seed in the fall.

The recent hot, dry weather has not helped with establishment and there’s not currently much going on in the plots. So we are back to waiting and seeing.

And crossing our fingers that the forecast holds and we get rain by the weekend.

At the end of June, after a week of heat and humidity but no rain, there is not much flowering except for birdsfoot trefoil. For the record, birdsfoot trefoil was not in any of our seed mixes.

Many thanks to Cornell Cooperative Extension Albany County for use of the site, Lindsey Christiansen for her partnership and strong back (and for checking my math), and Matt Warnken for scalping, hauling, sod cutting, photographing, and basically making himself indispensable.

Our 2018-2019 Annual Report – Nematodes, Spotted Lanternfly… a last Look and Recap

Today we reach the end of our in-depth look at our most recent annual report from the New York State Integrated Pest Management Program. While many of you receive it in the mail, the large number of in-person sharing we generally do as we speak with people around the state was obviously limited. We continue to do our best to reduce risk from pests and treatments, and to reduce the risk of Covid-19.

WE LOOK FORWARD TO A RETURN TO THE MANY WORKSHOPS, PRESENTATIONS, ON-SITE EVALUATIONS and GATHERINGS THAT WE VALUE AS PART OF OUR FOCUS!

Nematodes Go to School

For decades, researchers and practitioners alike have played around with beneficial nematodes to control insect pests in turf and agricultural crops. These nematodes are microscopic worms that move through soil looking for host insects to infect. Once inside a grub or other insect, the nematode releases bacteria that feed and reproduce, eventually releasing a toxin that kills the host. As an added bonus, nematodes often persist for years in the soil after just one application—they’ve been shown to permanently establish in both alfalfa and corn. Nematodes are an ideal biological control agent because they occur naturally in soil and can be applied to boost pest control. Now these tiny but mighty native worms have been enlisted to help protect school playing fields from pests, and to help teach science, too. Dr. Kyle Wickings, a Cornell entomologist, has been using native New York beneficial nematodes on school playing fields to target grubs, and to reduce the need for pesticide sprays. NYSIPM staff teamed up with him to train teachers in four school districts to add nematode sampling to their science curriculums. In addition to student-collected data, the team inoculated eight playing fields at three schools and then sampled the fields in the fall for signs that the little worms were sticking around. To date, results have been too variable to make recommendations, but our researchers—as tenacious as these worms—will keep on testing.

(Above) Students learned that these beneficial nematodes (round worms) might be hard to see without a microscope, but are hard at work attacking grubs in the soil under the playing fields. David Chinery, Horticulture and Turf Educator at CCE Rensselaer County, helps this middle school teacher get her hands dirty.

Here, during our Nematodes in the Classroom Workshop, she sifts through soil for dead wax worms that indicate whether nematodes are present and successfully parasitizing insects.

The Spotted Lanternfly: They Get Around

Hailing from Asia, the spotted lanternfly (SLF) arrived in Pennsylvania in 2012 on landscaping stone. They’ve been ravaging vineyards and making a mess of backyards ever since. SLF are clumsy fliers but adept hitchhikers. They lay their eggs on practically any hard surface—wood, rusty metal, railroad cars, and shipping containers are all fair game. SLF has been called, “the worst invasive we’ve seen in 100 years.” Of their arrival here, New Yorkers now say, “It’s not a question of if, but when.” A bright spot is the incident command structure formed by New York’s Departments of Environmental Conservation, Agriculture and Markets, and Parks. They started preparing early, and asked NYSIPM to help with outreach and awareness. Our goal? Immediate identification and education to prevent SLF establishment for as long as possible. Delaying their imminent debut gives us more time to inform the public, while allowing researchers to expand the management toolkit—including the use of natural enemies. We’ve created pest alerts, online courses, identification guides, YouTube videos, slide sets, and webinars. NYSIPM talks about SLF a lot. In the first year our staff mentioned SLF in more than 60 presentations, alerting nearly 2,500 participants representing the grape, wine, apple, hops, ornamentals, vegetable, berry, turf, and landscape industries. The good news? The efforts seem to be working. At the time of printing, a few SLF have been sighted in New York, but no infestations found. We want to give a shout-out to our friends in Pennsylvania who have generously shared information, and to New York’s government agencies and extension educators for getting the word out.

In closing, our annual report is an important part of our program because it showcases our service to our stakeholders and justifies the trust of our collaborators and funders. Highlighting many, but not all, of our accomplishments takes time. Collecting the stories and photos–after narrowing down the list of ideas–and then writing concise and interesting stories is the work of our director and commodity directors. After the retirement of our lead staff writer, Science Writer Mary Woodsen, we want to thank Mariah C. Mottley for her contribution!

Comments Off on NYSIPM partners with The Tick App

NYSIPM partners with The Tick App

The Tick App: Studying human behavior, tick exposure and the risk of Lyme disease using a citizen science approach via a smartphone application.

picture titled The Tick App has a picture of the app open on a cell phone

Concerned about ticks? Download The Tick App for free to join our research efforts and report your tick encounters.

If you have heard any NYS IPM Program staff talk about ticks, you have probably heard us mention that there is a lot we don’t know about ticks. Or exactly how our actions impact our risk of getting a tick-borne disease. So it is with great pleasure that we announce that we have partnered with the Diuk-Wasser lab at Columbia University and the University of Wisconsin-Madison who created The Tick App.

By downloading the app through GooglePlay or the AppStore, you will have access to information about:

  • ticks biology and identification
  • tick activity in your area
  • tick prevention
  • how to remove a tick

It will also help you identify ticks that you find through the Report a Tick button.screen shots from The Tick App

That’s a lot of information at your fingertips. The most important part of the app, however, is the daily log where you share with the team how you spent your time, what steps you took to prevent tick encounters (if any), and if you found a tick on you, a family member, or a pet. Your information is confidential and will only be shared as aggregated data based on zip code.

I have been using the app for two years and have made entering my data a daily routine, along with my daily tick check. It takes only minutes to complete.

The more people entering data, the better the team will be able to connect the dots between what we do and how that brings us in contact with ticks. We will then be able to better create recommendations to keep New Yorkers safe.

And there’s no better time as The Tick App is launching the #BattleOfTheDailyLog this June, pitching NY against other northeast and midwest states. C’mon New York! We can do this!

Don’t worry. We’ll still continue to provide tick information through the Don’t Get Ticked NY Campaign via our website, blog posts, and presentations.

It’s New York Invasive Species Awareness Week

The mission of the New York Invasive Species Awareness Week (ISAW) is to promote knowledge and understanding of invasive species and the harm they can cause by engaging citizens in a wide range of activities across the state, and empowering them to take action to help stop the spread.

While we won’t be able to gather for invasive species identification walks, removal projects, or in-person presentations, there are plenty of online opportunities to increase awareness. And the good news is that you will have access to statewide opportunities. Presentation topics run from learning how to identify plants information and enter it into iMapInvasives to the more specific info on beech leaf disease, crayfish, “murder hornets”, how climate change, and deer, impact native plants and pave the way for invasives, and more. For a full list of virtual events, visit https://nyisaw.org/events/.

And there are numerous challenges offered this year. Be sure to use the hashtag #NYISAW! ISAW Social Media Challenges, many suited for the kids, include:

Sunday – learn about your local invasive species and share a selfie

Monday – create some Invasive Species Art!

Tuesday – use the Agents of Discovery app to learn about invasive species

Wednesday – increase others’ awareness by creating a banner and hanging it in your window

Thursday – help track invasive species in NYS through iMapInvasives. New to iMap? There will be an online training at 1:00

Friday – spotted lanternfly is on our doorstep, if it’s not already here undetected. Check out spotted lanternfly trivia and help keep track of this destructive pest. (For more information, visit NYSIPM’s Spotted Lanternfly webpage.)

Here are a few other challenges that caught my eye:

The New York City Department of Environmental Protection has created the Invasive Species Backyard Bingo Challenge. I have (alas) seen many of the invasive species, but not enough to get BINGO (yay?).

The Capital Region PRISM has an EcoQuest Challenge focusing on watercress, European Frog-bit, oriental bittersweet, and swallowwort using iNaturalist.

Lower Hudson PRISM Ecoquest Challenge is focusing on Siebold’s and linden viburnum. They recommend using the Seek app to help build your identification skills and confirm your ID.

The NYS Parks Niagara Region is also using the Agents of Discovery App. They will post details on their Facebook page during ISAW.

These challenges, and more are also listed on https://nyisaw.org/events/.

And, of course, the NYS IPM Program has numerous resources on invasive species, including numerous blog posts we have written about invasive species and the recordings from our 2017 Invasive Species Conference.

So download the Seek app, head to the backyard and identify some invasive species. Upload the information to iMapInvasives. And then feel free to remove them. This weekend I’ll be CAREFULLY digging up wild parsnip along my roadside. How about you?

Comments Off on World BEE Day 2020

World BEE Day 2020

Protecting bees and other pollinators has become an important social issue. But beekeeping, and the 20,000 species of bees worldwide, have been providing livelihoods, much of our food supply, and important biodiversity for thousands of years.  Today, we help celebrate the first official World Bee Day as proclaimed by the U.N. through their food and agriculture organization.

poster of world bee day

We’ve collected some of our blog posts supporting pollinator protection (see below). First, here’s some facts from the UN’s Food and Agriculture Organization:

HONEY: Honey is a nutritious, healthy and natural food produced by the bees. Its benefits go beyond its use as a sweetener as it contains several minerals, enzymes, vitamins and proteins that confer unique nutritious and organoleptic properties. Honey can be monofloral if one specific plant nectar and pollen content prevails in pre-defined percentages or polyfloral if it contains an unspecified mix of different nectars and pollens. Due to environmental, geographical and climatic conditions honey may vary in pollen content and relative humidity. Honey is produced in all five continents and its consumption varies from country to country also due to cultural reasons and eating habits.

HIVE PRODUCTS: Honey bees may provide livelihood or a source of income for many beekeepers all over the world. This could happen through the services provided by the bees (mainly pollination service, apitherapy and apitourism), or directly through the bee products. The last include: alive bees to guarantee always new queen bees or bee packs, honey, pollen, wax, propolis, royal jelly and venom. Bee products may be used as food for humans, feed for animals, cosmetics, medicines used in conventional medicine (mainly vaccination), or in apitherapy, or other like manifold products, carpentry, attractant, sweeteners, etc.

benefits of pollinators poster

POLLINATORS: Disappearing pollinators can mean losing some of the nutritious food we need for a healthy diet. The decline of pollinators could have disastrous effects for our future of food. Their absence would jeopardize the three-quarters of the world’s crops that depend at least in part on pollination, including apples, avocadoes, pears and pumpkins. And enhancing pollination isn’t just about mitigating disaster – with improved management, pollination has the potential to increase agricultural yields and quality. Pollinators also play a crucial role in maintaining and enhancing biodiversity thus improving the resilience of plants to climate change and other environmental threats.

Asian Giant Hornets – A Concern for New York?

A pinned specimen of a large wasp, the Asian giant wasp from a side view.

By now many Americans reading or watching the news have heard about “murder hornets” from Asia invading the American landscape. It is true that in many parts of East Asia, Japan in particular, a large hornet lives and feasts upon honey bees and other insects. This is the Asian giant hornet (AGH), or Vespa mandarinia, which is a relative of the European hornet (Vespa crabro) that we typically see in North America. The European hornet is an import to America that has naturalized, or become established here as if it was native. The Asian giant hornet has just arrived on North America’s west coast, by unknown means. Residents and beekeepers alike are hoping it doesn’t become naturalized in America.

Pinned specimen of the large black and yellow Asian giant hornet, seen from above.

The Asian giant hornet is the world’s largest, measuring 1.6 to 2 inches long, with a particularly large yellow-orange head. It is a social insect, living in colonies built in soil burrows dug by rodents and other animals. While people may not often see Asian giant hornets, beekeepers will definitely notice their decimated colonies of honey bees. It takes a handful of Asian giant hornets to slaughter an entire honey bee colony, after which hornets feed on the larvae, pupae and honey inside the hive. Japanese honey bees, which are a different species of honey bee than what we raise in North America, can fight back against AGH by surrounding and super-heating the wasp in a ball of bee bodies. Our European honey bees do not have this defense behavior. If AGH becomes established in the US and Canada, the greatest threat will be to beekeepers and their honey bees.

The hazard to humans posed by the stings of AGH is real. The venom is toxic and with their long stingers, AGH can inject more venom into a wound than most other stinging insects. Stings lead to intense pain and swelling, and can induce renal failure and anaphylaxis. Multiple stings can be deadly. But, these hornets do not come after humans and left alone, they mind their own business. The efforts to eradicate AGH from Washington State and Canada will be a priority aimed at avoiding their permanent establishment in the US. Unlike claims in some media outlets, it will likely take many years for this wasp to spread across the country on its own if we fail to eradicate it. Beekeepers will be on the front lines of detection.

*** 2020 UPDATE – A dead queen Asian giant hornet was discovered this spring on a road near Custer, WA, which is close to the western Canada border. This indicates that queens produced by at least one colony in the Fall of 2019 overwintered and emerged. To date (6/3/20) no other detections have been reported.

There are several species of wasps in the US that are very commonly confused with AGH:

Cicada KillerSphecius speciosus – a large, native, solitary wasp, does not readily sting or act aggressive toward humans, hunts cicadas, exclusively, digs burrows in the soil where eggs are laid upon the body of paralyzed cicadas. Common in suburban areas.

A cicada killer wasp rests on a green leaf.

European HornetVespa crabro – an introduced social species, colonies started by a single queen, colony builds and expands a tan paper ball nest typically in hollow trees and abandoned barns and structures. More common in rural areas. Not aggressive unless harassed.

Baldfaced hornetDolichovespula maculata – Large black-and-white wasp, not a true hornet, colonies started by a single queen, nest is a grey paper ball usually high in trees or on the side of structures. Not aggressive unless harassed.

Yellowjackets (many species) – Vespula sp. – Small yellow-and-black wasps that nest in large colonies in soil and other man-made cavities. Can be aggressive, especially in early fall.

Paper waspsPolistes sp. – Slightly longer than yellowjackets, various colors, long legs, umbrella comb nest with a few to a few dozen wasps. Not aggressive unless harassed.

The Bottom Line: A few Asian giant hornets were discovered in Washington State in 2019. The greatest threat is to honey bees and beekeepers. Efforts to eradicate this wasp are underway. New York does not have Asian giant wasps and hopefully won’t anytime soon.

Residents of the west coast should keep an eye out for Asian giant hornets and residents of Washington State are strongly encouraged to submit reports of sightings to the Washington State Department of Agriculture. If you live in New York and have questions about wasps or any stinging insects, you can contact NYSIPM or your local Cornell Cooperative Extension office for advice or to submit samples for identification.

Our 2018-2019 Annual report: #3 Corn Earworm and Just What is a ‘Short Course’?

The Year of the Corn Earworm

Nobody likes opening an ear of corn and finding uninvited worms; not customers, and definitely not the grower! Wormy corn can lose customers at the farm stand and in wholesale markets, and can be a problem in both frozen and canned supermarket products. To help growers manage these pests, NYSIPM—in partnership with our Cornell Cooperative Extension colleagues—has supported a network of pheromone traps since 1993. These traps help track the flights of the moths that lay the eggs that hatch into these worms.

In 2018, the trap network alerted growers to an over-the-top population of corn earworm, one of four major sweet corn pests. And because IPM spray recommendations for this pest are based on trap catch numbers, that important data helped New York growers respond effectively to this serious threat to a 33 million dollar crop grown on 26,700 acres. Unfortunately, when a grower or processor finds worms in harvested corn, it’s too late to act—but accurate ID can inform plans for the following season. Essential to success is deciding if and when to spray using the appropriate scouting methods and thresholds for each pest. But accurate ID? Easier said than done! Caterpillars can be hard to identify, especially smaller ones. That’s why we developed a larval ID fact sheet highlighting critical distinguishing features. It’s just another piece of essential information in the quest for worm-free ears.

photo of corn earworm on ear of corn

(Above) Corn earworm invades the ear within hours or days of hatching from eggs laid on the silk, leaving no external damage. For this pest, scouting is ineffective. Pheromone traps that monitor adult flight are the grower’s best defense.

“I” is for Identification.

Good IPM starts with accurate pest identification—ID for short. Whether you see a pest or the evidence it leaves behind, correct ID is essential. Once you know what you’re dealing with, you can determine where it’s coming from, the risks it poses, and what conditions must change to eliminate it. Good ID makes IPM work. Even people who deal with pests all the time need to brush up on their ID skills, so we developed a Structural IPM Short Course to hone the diagnostic skills of pest management professionals, Master Gardeners, and others. Participants attend photo-filled lectures and get their hands on hundreds of real specimens. Critters are grouped by guild—their basic ecological niche—such as food pests, moisture-lovers, or blood-feeders. And specimens aren’t just bugs. Rodent droppings and gnawed wood get examined too. To aid learning and retention, we created a companion manual. We’ve offered the course 21 times, teaching the ABCs (you know: ants, bed bugs, and cockroaches) to over 700 people. And our learners learned: over three quarters gained knowledge of pest biology, while 100% improved their ID skills. We identify that as 100% good news for everyone but the pests.

Earth Day 2020 – IPMers Consider 50 Years of Concern and Action (part #1)

From Livestock & Field Crops IPM Extension Area Educator KEN WISE:

What I remember the most of Earth Day is when I taught high school forestry and fishery. On Earth Day, we would plant several acres of Douglas fir seedlings or release salmon in rivers with my students in the Cascade Mountains. We would grow our own seedlings and had a built our salmon hatchery.

Earth day for me is an everyday state of mind. My work in a small way I hope helps sustain the land.

From Community IPM Extension Area Educator MATT FRYE:

In grad school I coordinated an annual trash removal project in our woodlot, and prior to that I helped with tree plantings. But it’s been a few years, so this is more of a reflective thought on Earth Day…

Earth Day for me is a reminder. It’s a day to slow down. To take a deep breath. To experience and admire the wonders that this world has to offer. Equally, it’s a call to action. For if we fail to nurture and actively protect them, someday those wonders may be but a memory.

From Ornamentals IPM Coordinator BETSY LAMB:

To me, it is the power of people coming together for a cause.  And sometimes even people on apparently opposite sides of an issue who see that environmental improvements actually have benefits for both sides.

It is easy now to say that it is just a meaningless ‘holiday’ but we need to be reminded of how far we have actually come and what some of the changes have been and are.  Like some other issues, the changes have become the expected norm – which is perhaps a victory in itself.  And that is not to say that there are no longer challenges.  There certainly are – and some new voices pointing them out and encouraging new responses.  Hope, frustration, action, and change!

Each year, we plant a tree with the boys to celebrate Earth day. We try our best to educate and raise awareness, especially to our future generation(s), on the importance of unity and coming together to protect and nourish our global home.

“if you want a child’s mind to grow, You must plant the seed.”

Happy Earth day!

From Community IPM Educator LYNN BRABAND:

Here is a photo of my participation in the first Earth Day as a sophomore in community college. I am at the red arrow. I was one of the organizers of the day’s activities in that municipality. Personally, the event was part of a journey that I was already on.

Tomorrow, we’ll be sharing a few more thoughts on the significance of Earth Day. Thank you to Jennifer Grant and Joellen Lampman for helping to pull this post together!
