Fire Improves Bird Habitat at Ganondagan State Historic Site

Have you heard about wildfire outbreaks in California or New York on the news? Do you know how a prescribed burn and wildfire differ from one another?  A prescribed burn is very different from a wildfire. Prescribed burning is a management tool that is precisely planned for safety and meeting set goals, while wildfires often occur unpredictably and without warning. State Parks utilizes prescribed burning for both public safety and conservation purposes. This past spring, at the Ganondagan State Historic Site near Rochester, prescribed burning was used for both conservation and to replicate traditions of the Seneca people.

Ganondagan State Historic Site (Ganondagan) celebrates and interprets the lives and culture of the Seneca people, specifically the Seneca that lived on site between 1655-1687. The site is 570 acres, and in 2009, a 70-acre portion was set aside for grassland management. Journal entries from European visitors during the time of Seneca occupation, described the areas surrounding Ganondagan. In 1669, explorers Galineē and Dollier described vast oak openings with sparse, but lofty, oak trees and grasses taller than a man that extended for hundreds of miles in every direction.¹ These observations paint a picture of warm season grasslands, with grasses reaching heights of 8 feet or taller, sparse wildflowers and oak trees around their fringe.² Warm season grasses begin growing in June, reaching full maturity by August or September. Some of the earliest observations indicate that the Seneca people burned these grasslands annually, managing them to attract game animals and birds, and to facilitate nut collection.³

The 70 acres set aside for grassland management began its transformation in 2009, with the goal of recreating the landscape that existed for the Seneca at Ganondagan almost 400 years ago. A fully established warm season grassland can support many forms of life, and at Ganondagan it is a haven for rare grassland bird species. Grasslands are ecosystems maintained by natural disturbances like fire. Without disturbance, a grassland will gradually go through the steps of succession to become a shrubland and later a forest.

Before the prescribed burn at Ganondagan in May 2017, the grasslands had begun to build up a thick thatch layer, decreasing both the amount of sunlight reaching its sun-loving plants and the amount of bare ground between plants (which grassland birds and mammals like for habitat).

Time of year can play an important role in how an ecosystem reacts to a burn. At Ganondagan, a spring burn was chosen to cut off early growth of invasive species and to promote the growth of the warm season grasses like big bluestem and Indian grass. Future prescribed burning done on the site may happen in different seasons depending on the desired outcome. For example, a prescribed burn taking place in this warm season grassland in the fall would promote the growth of forbs (broad leaved plants), such as wildflowers. Regardless of the timing, a properly done prescribed burn will not completely remove grasses or forbs, but can help achieve the best plant composition for grassland birds.

Prescribed burning was the perfect way to manage the grasslands at Ganondagan: it created a disturbance to maintain the ecosystem, returned carbon and nitrogen to the soil in the form of ash, and opened the grassland to more sunlight. This burn also provides a unique opportunity for educators to interpret this management tool, once used by the Seneca at Ganondagan to maintain the grasslands in the 17th Century, and now updated for the 21st century!

This valuable management tool will continue to be used at the Ganondagan State Historic Site and are exploring future opportunities.

The Petaltail’s Tale

Each June and July, visitors to several gorge parks are rewarded with an unusual treat – the chance to see a “living fossil.”

The term “living fossil” refers to species that have evolved very little over the course of millions of years. Some well-known examples of living fossils include elephant sharks, ginkgo trees, and horseshoe crabs. Although all of these organisms have evolved, these species have stayed so similar that fossils from millions of years ago are still recognizable as ancestors to the modern species.

Meet the gray petaltail dragonfly (Tachopteryx thoreyi), a species of dragonfly that closely resembles its ancestors who were around when dinosaurs roamed the earth during the Jurassic Period – almost 200 million years ago!  During that time, the petaltail dragonfly was part of very widespread family known as the Petaluridae. Today, however, there are only 11 species of Petaluridae remaining worldwide.

The gray petaltail is found in several of the Finger Lakes gorge parks the gray petaltails love hunting in the gorges, because they can go to the sunny side of the gorge to get warm, which allows them to move much faster.  Petaltails are drawn to the gorges to lay their eggs in the soggy seeps on wooded slopes. Most dragonflies lay their eggs in water bodies. The eggs grow into juvenile dragonflies, called nymphs that also typically live in water.  That is not the case for the gray petaltail nymphs! The gray petaltail is the only species of dragonfly that does not have fully aquatic nymphs. Instead, the petaltail nymphs live and grow while hidden in the mud, moss and moist leaf litter in the forest seeps. As the nymphs mature, they climb up the trunks of trees to become the adult dragonflies that can fly fast and free all around the gorge.

While they are not nearly as large as their Jurassic ancestors, today’s petaltails are one of the larger species of dragonflies, with a wingspan of up to 5 inches wide.  Their distinct black and gray coloring also makes it easy to identify.  This species often perches upon rocks and tree trunks, but it is not uncommon for it to perch upon a passerby! Although they are large and ferocious insect predators (eating thousands of mosquitoes), dragonflies are harmless to humans. If you are lucky enough to be chosen as a dragonfly perch, you may be startled, but either brush them away very gently or just enjoy it!

The gray petaltail is listed as a species of special concern within New York State, as it is only known in specialized habitat in a small number of locations.  NY Natural Heritage Program (NYNHP) continues to survey for them and recently found another new site for them. Luckily, some of those locations are within New York’s state parks, providing habitat protection to this fascinating species – and maybe a chance to see this primitive insect for yourself, especially in June and July.

Wildlife Spotlight: Furbearer frenzy: The Mink

Scientific name: Mustela vison

Small predator furbearers are some of the most fun, and most uncommon, animals to see in the wild. And mink are some of the most secretive in this group! Minks are in the weasel family and can grow to about the size of a housecat. Unlike weasels however, mink do not change color in winter. Mink are generally dark furred, with a distinctive white patch on their chins. Mink seem to be more common in the southern tier of New York State, so keep an eye out for these adorable buggers on your hikes in that area.

Mink were traditionally prized and trapped for their soft, glossy coats. Mink coats were a status symbol in the early 20th century, with most coats made from wild-caught mink. However, the 1950s through the 1970s saw a large increase in the production of farmed mink, especially from Europe, which reduced the burden on the wild populations. Today, trapping licenses for mink are available through the NYS Department of Environmental Conservation (DEC), and the season is open when the population can withstand normal trapping pressures. DEC reports that the mink population is stable and able to sustain the trapping that still exists.

Mink are excellent swimmers, and they can also climb trees. Their clawed and webbed feet make them versatile predators. They are opportunistic predators, meaning they prey on crayfish, frogs, lizards, eggs, earthworms- pretty much anything they can find! They prefer wetland, or stream habitats, and will actually use existing burrows for their dens. They prefer muskrat holes, and some individuals have even been reported to evict (and eat) a resident muskrat to use a preferred hole.

Don’t forget to report mink and any other furbearers you see to DEC, to help with annual population data collection on these seldom seen species:

Autumn is such a great time to enjoy the outdoors in our State Parks.

Outdoor Activities in State Parks: Hunting

Among the many recreational outdoor activities available in our state parks, hunting is one that many may overlook. Hunting is a long-standing tradition in our nation, both as a necessity and an opportunity to be connected with the outdoors. Hunting is a safe and economically important activity; providing an excellent source of food and promoting family traditions while nurturing an understanding and respect for the environment and the complexity in which it functions. Today, an individual looking to take advantage of hunting opportunities must first complete a hunter safety course, and obtain a hunting license.  The hunter safety course will provide instruction on firearm/ bow safety and planning a hunt, by providing information about the biology of the game species in New York State.

During this fall season many New York residents and out-of-staters will venture out into the woods and wetlands to take part in the multiple hunting seasons that New York State has to offer. Among the vast huntable acreage across the state are properties managed by the Department of Environmental Conservation (DEC) and New York State Parks. In State Parks alone there are about 80 parks, 3 historic sites, 3 golf courses and 50 boat launches that provide opportunities to hunt an array of wildlife from small game, waterfowl to big game species like bear and deer.

Being a hunter – what does it take?

Let’s take a step back and investigate what is involved in becoming a hunter. Besides the hunter safety course and a New York State Hunting license, the hunter must understand the biology of the animal and how that animal interacts with its habitat. Hunters have to be keen observers in order to be successful. Let’s learn about some of the signs a hunter looks for when pursuing whitetail deer.

Deer Path: Deer tend to travel through the forest in a path of least resistance – clear of downed trees and shrubs. Over time these paths become visible as the deer travel them regularly, just like a hiking trail.

Tree Rubs: Male deer, or “bucks”, will make rubs on small trees with their antlers to mark their territory, deposit scent and declare their presence to other deer. A hunter must look for rubs in the woods and learn how to tell the difference between and old rub and a new rub. This can be done by closely looking at the tree. A new rub will have the presence of shavings or sawdust on top of the leaf litter that are scraped off when the buck makes a rub. Additionally a new rub will be contrastingly much lighter in color compared to an old rub that is weathered and darker.

Scat: Where deer eat, they poop! A hunter will look for fresh scat (poop) as evidence of recent activity. Fresh scat will be on top of the leaf litter – whereas old scat will be noticeably under leaves and sticks.

Sounds: Deer make a variety of sounds including a soft bleat, grunting, stomping with their hooves, and blowing air. The varying sounds and body language have different meanings. For example a deer may stomp their hooves and blow air out their nose when they smell or see a person in the woods. Observing how deer interact with each other and the sight and scent of humans helps a hunter better understand deer behavior.

A hunter should look for signs of deer well before the hunting season begins to learn the habits of the animal he/she is hunting. Equally important is practice, practice, practice! To be proficient with a firearm or bow a hunter must hone their skills year round. Hunting isn’t easy, it takes practice, time and a lot of patience to be successful. There are many hunter safety education courses available through DEC including the popular “Becoming an Outdoor Woman” (BOW) series. Take a look for yourself.
