A Conservation Cornerstone Celebrates 20 Years

This year, the New York State Bird Conservation Area (BCA) Program celebrates its 20th anniversary. Since 1997, the BCA Program has been promoting the conservation of birds and their habitats on designated state-owned lands and waters in New York State. There is no other program like it in the United States. The BCA Program is modeled after Audubon’s Important Bird Area (IBA) Program but is backed by legislation.  Sites are considered for BCA designation if they meet criteria relating to high concentrations of birds, bird diversity, or the presence of at-risk species. Recognizing a site as a BCA brings awareness to the needs of birds on state-owned lands and encourages management that benefits the bird populations. While the BCA Program focuses on birds, the program also benefits other species that share the same habitats.

Audubon has partnered with the New York State Office of Parks, Recreation and Historic Preservation (State Parks) on the BCA Program since its beginning, and has held up the BCA Program as a model for other states to protect birds. This fall, Audubon was delighted to join State Parks in celebrating the 20th Anniversary of the program, in conjunction with the designation of the 60th BCA in Ganondagan State Park.

In recent years, Audubon’s partnership with State Parks has expanded to include Audubon in the Parks initiative, which is a partnership with Audubon New York, State Parks and its Regional Commissions, Audubon Chapters, and friends groups to advance bird conservation in State Parks, specifically focusing on BCAs and IBAs. Through Audubon in the Parks, Audubon assists with the implementation of BCA management recommendations, conducts bird monitoring, and helps with other strategies and research activities that benefit priority birds and habitats. In addition, Audubon advocates for funds to ensure that habitats are preserved and managed in a way that benefits priority birds and further connect people to these unique places.

Through Audubon in the Parks, Audubon has been active in more than 50 State Parks across the state, including 20 BCAs. This successful initiative continues to grow through projects like the one recently completed at Schodack Island State Park, which has been designated as a BCA because of nesting Cerulean Warblers and wintering Bald Eagles. Led by the Audubon Society of the Capital Region, this BCA project included building bird blinds for visitors to view birds without disturbing them and removing invasive species within the park. The chapter continues to foster a community connection to the park and importance of this BCA by hosting eagle walks and other events such as the recent Schodack Island Raptor Fest.

The Mysteries of Fall Foliage Revealed

Have you ever wondered what makes the leaves change color in the fall? Or why some years are more vibrant than others? It is quite a fascinating phenomenon, and it all starts with the seasonal temperature and day light hour change. In the fall, the days become shorter and the evenings become cooler. This is what triggers deciduous trees (trees that lose their leaves in the winter) to begin their process of preparation for the winter months to come. This is also why the foliage changes color around the same time every year.

It starts with the expansion of the abscission layer between the stem and leaf, which slowly blocks the movement of water and sugar back and forth between the leaf and stem. This causes the leaf to lose the ability or resources to replenish chlorophyll, which gives leaves their green coloration. The chlorophyll rapidly breaks down and we are left with xanthophylls and carotenoids, which are responsible for the yellow and orange pigments you see on trees like aspen and birch. These pigments are usually present in the leaf throughout the growing season but are masked by the green pigment of the chlorophyll.  Anthocyanins are responsible for red and purple coloration and are created by the buildup of sugars trapped in the leaf. As fall progresses into winter all of the other pigments break down, as the chlorophyll did, and the only pigment that remains are the tannins, which are responsible for the brown color of the fallen leaves – though some trees retain their brown leaves throughout the winter, such as oak and beech.

Factors that affect the color and duration of fall foliage are temperature, sunlight and moisture. Ideal conditions for colorful fall foliage are a good growing season followed by dry, warm, sunny days and cool nights. If there was stress in the growing season, such as a drought or flood, the abscission layer may form early and the leaves will fall off before changing color. Additionally, too low of temperatures (freezing) in the beginning of fall will rapidly break down the products responsible for bright colors and the only pigment left will be brown. Other factors that can affect colorful fall foliage are heavy rain and windy storms, as these conditions will cause the leaves to fall.

When you are out admiring the fall colors this year, try to identify which pigment products are responsible for the colors you are seeing on the trees. A great way to view the fall foliage is from a canoe or kayak, but remember to wear your personal floatation device as the water will be chilly! The New York Fall Foliage Report is a great tool for tracking the color changes across the state: http://www.iloveny.com/seasons/fall/foliage-report/#.VgQGwstVhBd.

See Through the Eyes of the Seneca at the Ganondagan Grassland Management Area

The Ganondagan State Historic Site located in Victor, NY boasts a historically accurate 17th century longhouse and will be opening a new Seneca Art and Culture Center this fall. However, there is a hidden gem at this historic site that not many realize exists! It is the Grassland Management Area at the corner of Boughton Hill Road and School Road which covers around 80 acres (over 60 football fields!) and is one of the most intriguing interpretive areas at the site!


In 2009 OPRHP restored 67.4 acres of the Grassland Management Area to represent oak opening communities in both plant composition and spatial arrangement. The Grassland Management Area has since spread to fill around 80 acres with the native plants seeded back in 2009.

The idea behind creating an oak opening came from Ganondagan’s past. Journal entries from French and English visitors to the site in the mid to late 1600’s described the landscape they saw when visiting the flourishing Seneca town of Ganondagan. Their descriptions of oak openings were used to create a scene that can transport the viewer back in time to when the Seneca were living at Ganondagan 400 years ago!

Oak openings are fire-dependent savannahs (grasslands) dominated by oak trees and are rare ecological areas, especially in upstate New York. The oak opening created at Ganondagan consists of warm-season grasses (grasses that thrive in the heat of the summer), wildflowers and large oak trees along the surrounding wood edge. Spring fire management promotes lush growth of warm-season grasses and oak trees. Controlled fires also suppress grassland succession (gradual changes in plant species in an ecosystem), provide fertilizer in the form of plant ash, reducing plant height to allow sunlight to reach new (young) plants and hinder the development of invasive species. The fire management of oak openings such as the Grassland Management Area have historically maintained their species composition mainly due to wildfires, to utilize this historic management technique OPRHP will be conducting a prescribed burn. A prescribed burn is a well-planned fire managed by trained firefighting professionals with specific plans in place to keep smoke high and away from the public.

Proper permits and permissions have been received for OPRHP staff to conduct a prescribed burn at the Grassland Management Area in spring of 2016. The burn will cover 20 acres in the first year and help maintain the plant communities of the Grassland Management Area that are representative of the Town of Ganondagan in the 17th century.

When you visit  Ganondagan’s oak opening, look for native plants include big bluestem (Andropogon gerardii), little bluestem (Schizachyrium scoparium), Indian grass (Sorghastrum nutans), black-eyed Susan (Rudbeckia hirta), tall white beardtongue (Penstemon digitalis), smooth blue aster (Aster laevis), New England aster (Aster novae-angliae), zigzag aster (Aster prenanthoides), and Indian hemp (Apocynum cannabinum).

Throughout the year, the grassland at Ganondagan are a delight to visit.  In spring, it is a lush open area of low, green grasses where chirps and buzzes can be heard above anything else. In the late summer it transforms itself into a beautiful 8-foot tall wonderland of wildflowers and golden brown grasses with different seed head patterns, where you can watch even the slightest of breezes wave through all 80 acres!
