Steve Young and Kim Smith of the New York Natural Heritage Program surveyed a state park in Ulster County this week. Besides Kim finding a new population of Carex davisii, these are some of the other things we saw.

A canoe trip to Franklin County by Wayne Jones resulted in the discovery of a new population of dragon’s mouth orchid, Arethusa bulbosa. It’s the tenth population known from the Adirondacks and the second one known from Franklin County. The other population in Franklin County (discovered in the 1990s) is the most northerly one in New York. Congratulations Wayne! Below are a couple of photos of the orchids, some of them were very pale in color.
This is another great Carex reference for New York with extensive illustrations, keys, comparison tables, and descriptions for each species. It was written by Dr. Lisa A. Standley, and has been published by the New England Botanical Club. To purchase, send a check for $26.00 payable to the New England Botanical Club to: Lisa Standley, VHB, 101 Walnut Street, Watertown MA 02472.
This photo from a saltmarsh on Long Island caught Phragmites in the act of spreading from one marsh to another. It probably happens under the cover of darkness but this crew was headed out in broad daylight.
Check out these fashions made entirely from leaves, fruits, and flowers! The artist calls them Weedrobes.
The website for the NY Natural Heritage Program Conservation Guides on rare species was hacked for use as a spam computer and the guides are temporarily offline as the situation is fixed. They hope to get them back online soon.
In a recent post we tested the new tree identification Apple app Leafsnap with 5 trees and it was right on two of them. Today we collected more species and tested it again. Here are the results with the number signifying the position of the guess.
1. American elm – 9. Second tree – 7.
2. Scarlet Oak – 1.
3. Swamp white oak – 1.
4. Red oak – 1. Second tree – 8.
5. White ash – 15.
6. Northern catalpa – 4.
7. White oak – 1.
8. Shadbush – 8.
9. Bigtooth aspen – 1.
10. Red maple – 3
11. Black oak – 5
12. Quaking aspen – 20.
13. Russian elm – 2.
13. Black locust – 4.
14. Black cherry – 8.
15. Box elder maple – 3.
16. White mulberry – 2.
17. Norway maple – 4.
18. Honey locust – 1.
A third of the trees were guessed right but the majority were misidentified, some of them badly. We can see why it might misidentify oaks because of the variety of shapes from tree to tree and on large and small trees. It seemed weird that it would miss easy ones like red, box elder, and Norway maple and quaking aspen, some of our most common trees. As an accurate way to identify trees we don’t think this app is quite ready for prime time.
