Invasive Species in WNY: the battle continues

April 29, 2009

Eighteen enthusiastic volunteers from SUNY-Fredonia and the Nature Sanctuary Society of Western New York visited the Alexander Preserve in Zoar Valley on April 25th to remove several invasive species within the Preserve in honor of Earth Week.  Target species of choice for removal were daylily and bush honeysuckle. Daylily is currently limited to a slowly expanding linear patch along the road just before the trail that leads to the bottomland portion of the Preserve.  At first glance, removing the daylily by hand with 18 people seemed possible, but the wet clay soils hampered our ability to separate the tuberous roots from the substrate and it was slow going. removing-daylily1 Some progress was made but we are re-thinking our strategy and making plans to return, perhaps to try another method. In the photos below, you can see a few trout lilies managing to flower among the daylilies.

Young bush honeysuckles are present in scattered patches throughout portions of the Preserve and these we simply pulled by hand.  It was somewhat gratifying (though with mixed emotions) to view the private property on the opposite side of the Cattaragus River, which has not been managed for invasive species, and realize the difference that vigilance in removing bush honeysuckle makes.

Rewards for the day included sightings of Frasera caroliniensis rosettes just emerging, bluebells beginning to flower, emerging garlic leeks, and flowering spicebush.  The landscape is undergoing a period of massive subsidence and several trees has split right up the trunk as a result of competing forces.  Quite an amazing landscape indeed.

National Phenology Network website

April 29, 2009

Besides the Central New York effort described below there is a national effort to monitor phenology.  From their website –  The USA National Phenology Network brings together citizen scientists, government agencies, non-profit groups, educators and students of all ages to monitor the impacts of climate change on plants and animals in the United States. The network harnesses the power of people and the Internet to collect and share information, providing researchers with far more data than they could collect alone. To join the network go to:

Visit Project Budbreak

April 28, 2009

What is Project Budbreak?   The web site has been established to help citizen scientists observe the effects of climate change on native plants in central New York.

Associated with a national effort, a network of citizen scientists is being established in central New York to observe the timing of flowering, leaf development, fruiting, and leaf drop in populations of common native trees and herbaceous species. This site will help observers to enter their data on the timing of important plant events through the growing season.

After registering as a participant, you will set up 1 or more sites that you will be observing regularly. For each site, you will set up 1 or more individual plants for which you will periodically record phenological data. – Information from the budbreak website.

This day will offer volunteers a rare opportunity to visit this beautiful area and contribute to it’s protection. Expect to see a large stand of bluebells (Mertensia virginica) and other spring flowers and incredible geology including mass wasting on a scale not often seen!  If you would like to join the group, please call Jon and Priscilla Titus at 716-679-4509 or Priscilla’s cell at 716-969-0800 before 8:30 AM on Saturday April 25th for directions to the site, or meet us in the SUNY-Fredonia Jewitt Hall Parking lot at 9:55 AM on Saturday to carpool to the site.
