KNPS Announces 2021 Research Grants for Students and Citizen Scientists!

Did you know that the Kentucky Native Plant Society offers small grants to help defer the costs of botanical research, inventory and native plant restoration? Since 2012, KNPS has awarded $8,100 to students working in these areas. Another $750 was awarded in prior years. The total number of grants awarded in any given year is based on the number of proposals received, the quality of proposals and available funding. The graph below shows the kinds of projects that have been funded.

The second type of grant is new and is open to anyone. It will fund

1.  native plant inventory, or

2.  rare and native plant restoration.

Native plant inventory grants are limited to Kentucky locations and successful applicants will receive a maximum of $250. Rare and native plant restoration grants are awarded to applicants working with native Kentucky plants, preferentially those which are globally rare (G1, G2). Successful applicants will be awarded a maximum of $500. All rare and native plant restoration grants require coordination with the Office of Kentucky Nature Preserves (OKNP) and the Kentucky Native Plant Conservation Alliance coordinators prior to application.

A grant proposal must include:

  1. A current curriculum vitae;
  2. A proposal (not to exceed two single-spaced typed pages) describing the proposed research and the role the grant would play in the research;
  3. An itemized budget;
  4. A letter of recommendation from the applicant’s major professor or project director; and
  5. Indicate whether the grant request is for a student research grant, a native plant inventory grant or a rare and native plant restoration grant.
  6. If the grant is for rare and native plant restoration, include a letter of support from OKNP.

Budget items typically funded include travel to research sites and supplies such as herbarium paper and lab consumables. No personnel time will be funded.

All Grant Proposals are due by March 15, 2021.

If you are interested in applying for any of the KNPS grants, visit the Grants page at the KNPS website. If, after reading the grants page, you have any questions, please email them to: grants@knps.org.

Hardiness Zones and Ecoregions

By Shannon Trimbolli, owner of Busy Bee Nursery and Consulting

Pick up almost any seed packet, read almost any gardening book, or attend almost any gardening class and you are likely to see a USDA plant hardiness map. The map was developed by the USDA and is based on the average minimum winter temperatures for an area. It divides the country into multiple zones with each zone representing a 10-degree temperature range. Each zone can then be further subdivided. So, for example, where I’m at in Kentucky is zone 6b with an average minimum winter temperature of between 0 and -5 degrees Fahrenheit.

The USDA Plant Hardiness Zones are based on the average minimum annual winter temperature. The zones were developed to help gardeners know what exotic, ornamental plants, vegetables, etc. would survive their winters. (Photo credit: USDA.)

The goal of the plant hardiness zones is to help gardeners determine whether a plant will survive in their gardens. This is especially helpful for exotic ornamental plants, garden veggies, etc. because in garden settings you can presumably control how much water a plant gets, how much fertilizer it gets, etc. However, temperature is the key component that we can’t control and which plays a major role in whether a plant can survive in an area.

The idea of plant hardiness zones and their importance is so ingrained in us that it is common for gardeners to automatically mention what zone they are in when discussing a new plant with other gardeners. This is a good thing because it shows that people are recognizing that the same plant can’t grow in all locations and the person is being conscientious of the growing limitations for where they live. But plant hardiness zones also have their limitations, and one of those limitations is their usefulness for discussions around growing native plants.

Obviously, if a plant is native to a given area, then it can survive that location’s average minimum winter temperature. However, just because a plant can survive an average minimum winter temperature doesn’t mean that it is native everywhere that average minimum winter temperature is found.

For example, parts of New Mexico are in zone 6b, just like I am in Kentucky. However, when I drove through those areas of New Mexico a few years ago, I didn’t see any of my familiar Kentucky native plants naturally growing there. Yes, in controlled garden settings with supplemental watering, people in New Mexico might be able to grow some of the plants that are native to Kentucky, but in that type of situation the Kentucky native plants are being grown as an exotic ornamental plant. They no longer count as a native plant, because they aren’t native to New Mexico.

When it comes to native plants, plant hardiness zones aren’t much use, which makes sense because hardiness zones weren’t developed with native plants in mind. In the world of native plants, ecoregions are what we need to use instead of hardiness zones.

Reflection on Land Conservation: Protection in Perpetuity

By Jody Thompson, Woods & Waters Land Trust

Care for the land transcends social, political and educational differences.

Throughout my career as a conservation professional, I have worked with many landowners—too many to keep up with, really—over the years. I take pride in that and consider myself fortunate to have worked with so many people who appreciate help expressing care for their land.

Through this, I learned many approach conservation differently. Many landowners want to play an active role in making habitat improvements. Others believe in a more preservationist approach of giving the land rest from human hands. Both approaches have their place, and even though they are different, they are rooted in the same goal of land conservation. Care for the land transcends social, political and educational differences.

Joining the work of Woods & Waters Land Trust now exposes me more to landowners with truly long-term conservation goals—protection in perpetuity.

To do this reliably—to ensure perpetuity of the forests and other lands that support our waters, wildlife and conservation lifestyles—private land protection must include legal protection, such as with a conservation easement. Whereas we want to believe our natural lands will always remain natural, it’s hard to ensure this. Land is sold every day for various reasons, and future owners, including our children, may not share our same land values.

Thankfully, a permanent conservation easement remains with the land and sets forth the allowed uses of the land. An easement held by Woods & Waters Land Trust, for example, is likely to state that forested areas must always remain forested and that future development, e.g., homes and other buildings, must be restricted to certain areas and well-defined.

Those who have completed the conservation easement process for their land have described a sense of relief and, in some cases, greater closeness than before. Connie May, a co-owner of a Woods & Waters Land Trust conservation easement property in Owen County, Kentucky, said she had an even greater connection to her land after permanent protection was in place.

Betty Beshoar described a duty to the world that she and Mark Roberts accomplished with their easement on the banks of Elkhorn Creek in Franklin County. And Don and Sylvia Coffey told us how their 43-acre easement in Shelby County laid the groundwork for how their land should influence future generations. 

These landowners have accomplished something for the forests and wildlife. They’ve provided something for their children that keeps giving and ensured that an aspect of their well-being is protected for the long term. 

Reasons for considering a conservation easement vary, and appropriately so. It can be protection for the land itself and the wildlife that call it home. It may be to ensure the land exists so others can learn from it and experience it. For others, protected lands are essential to mitigate the effects of nearby development and habitat loss.

Creating this kind of protection is a big decision. A survey, appraisal (if tax benefits are desired) and assessments can take time. Even with the firm belief that protecting rare plants, forests or family legacy is important, the process requires patience and a trusting partnership with the organization holding the easement. It’s common for misconceptions, like needing large acreage, having rare species present and the belief that they’re sharing ownership, to arise.

The first step to entering into a conservation easement is simply a desire to see natural lands remain natural. The second is the willingness to work with an organization dedicated to helping conserve the lands that are integral to our lives. Organizations like Woods & Waters Land Trust exist to help landowners through this process.

Land is more than an object to be analyzed and shaped. It’s personal, emotional, a home. The spring wildflowers, the trees, the rabbits, deer and songbirds are members of an inner community that together make up the land.

Protecting these places satisfies a visceral need that we have as part of the natural system. Because even with all the rapid, intense disturbance that occurs when humans expand, explore and live life, we are from the natural world. Conserving these natural places is essential to who we are and where we, as people, come from.

I’ve learned from getting to know landowners and listening to their stories that they understand they are part of something bigger than themselves. They’re playing the long game. And that’s a game I’m glad to have grown into.

It’s a beautiful experience to stand alone on a snow-covered streambank. It’s exciting to plan a new habitat improvement and know you’re shaping a better future for a natural space. It’s inspiring to walk in a wood that’s been cared for. But there’s a greater sense of peace on a land that is protected forever.

Kentucky Botanists Big Year 2020 Results

This was the second year KNPS hosted an iNaturalist Botanists Big Year for Kentucky. The Botanists Big Year is a friendly competition to observe as many different wild/naturalized plant species as possible in the state; it’s a great way to explore new natural areas, get to know your favorite nature preserves better, learn how to recognize hundreds of native species, and discover which ones are your favorites!

In 2020, 2,251 people made 17,919 research-grade observations of 1,298 species – way to go, Kentucky botanists! This year, John Abrams (@jabrams_foc) swept the #1 spot for both Most Species (374) and Most Observations (1,642).  

A few of John Abrams’ observations from 2020 (top row): Field milkwort, Polygala sanguinea; Buxbaum’s sedge, Carex buxbaumii; Dwarf sundew, Drosera brevifolia; (bottom row) Indian grass, Sorghastrum nutans; Soapwort gentian, Gentiana saponaria; and Ragged fringed orchid, Platanthera lacera.

Prizes and certificates will be given to the top five participants in three categories:

Most Observed Species:

  1. @jabrams_foc – 374
  2. @nyssa_ogeche – 283
  3. @kentuckybotanist – 241
  4. @biomania – 207
  5. @emwachter – 200

Most Observations:

  1. @jabrams_foc – 1,642
  2. @nyssa_ogeche – 414
  3. @emwachter – 343
  4. @robert1971 – 342
  5. @kentuckybotanist – 338

MVP Identifiers – many thanks to the folks that helped us get so many observations to Research Grade!

  1. @thomashulsey – 2,272
  2. @jabrams_foc – 1,827
  3. @davidenrique – 842
  4. @melanielinkperez – 670
  5. @polemoniaceae – 518

Since the inception of iNaturalist, 1,888 Research Grade plant species have been observed in Kentucky, but this does not represent the full extent of all plants known to occur in the state. In fact, there are several hundred of Kentucky’s plant species that have not yet been observed on iNat! Here are a few members of the state’s flora that made their “iNat debut” in 2020:

Notably, 2020 was a banner year for rare twining vines of the Pea Family (Fabaceae). Two of the most botanically exciting finds from Kentucky iNatters were the discovery of new populations of Price’s potato-bean (Apios priceana) by @kentuckycourtenay in Warren County, and Cream ticktrefoil (Desmodium ochroleucum) by @frank-lyne in Logan County. Price’s potato-bean is a globally threatened species that is similar to the common and widespread American groundnut (Apios americana), but Price’s potato-bean has larger, pinkish to pale purple flowers, whereas American groundnut flowers are smaller and deep maroon:

Cream ticktrefoil is a globally rare species, which is most similar to Round-leaved ticktrefoil (Desmodium rotundifolium). Both plants have a trailing habit, but Cream ticktrefoil has cream-colored flowers and oval-shaped leaflets, while Round-leaved ticktrefoil has pink flowers with nearly orbicular leaflets.

What native species did Kentucky observe most frequently across the months of 2020? Mid to late winter was prime time for orchid spotting: the most photographed native in January was Downy rattlesnake plantain, Goodyera pubescens (photo by @emwachter) and in February, the Cranefly orchid, Tipularia discolor (photo by @natebutcher). Longer days and warmer soils brings everybody’s favorite: spring ephemerals! In March, the most observed species was the dainty Cutleaf toothwort, Cardamine concatenata (photo by @bereahome):

In both April and (appropriately enough) May, the umbrella-like foliage and discreetly hidden flowers of Mayapple, Podophyllum peltatum was the most observed native (photo by @sillydog). In June Sassafras, Sassafras albidum (photo by @dalton28) was the dominant observation. This is a common native tree and a great species to introduce to young kids, as the crushed leaves of Sassafras smell just like Froot Loops cereal! In the heat of July, many of us were admiring the charms of the ubiquitous Common selfheal, Prunella vulgaris (photo by @frank_lyne):

Late summer belonged to the eye-catching orange blossoms of Spotted jewelweed, Impatiens capensis (photo by @hwisniewski), the most observed plant for both August and September. In October, the dense berry clusters of Pokeweed, Phytolacca americana (photo by @ellemaac) took center stage. And in the final two months of the year, the friendly evergreen foliage of Christmas fern, Polystichum acrostichoides (photo by @asherhiggins91) was still there to greet us on woodland walks:

For the entire year, the plant species that Kentuckians observed most in 2020 were:

1. Common jewelweed (Impatiens capensis) – 236 observations

2. Christmas fern (Polystichum acrostichoides) – 225

3. Tulip tree (Liriodendron tulipifera) – 223

4. Mayapple (Podophyllum peltatum) – 219

5. Red deadnettle (Lamium purpureum) – 214
