Central Park Botany Walk with Regina Alvarez, 6/1/2024

Registrar: Amanda Bielskas
Participants: 19
Weather: 78–82 F; Mostly sunny, N winds 5 mph.
Bird Species: 18

Eighteen Linnaean Society members and botany enthusiasts gathered on a warm sunny morning to wander in the available tree shade and light breeze around The Pool and The Ravine of northern Central Park. Regina Alvarez, the walk leader, with her familiarity and experience with Central Park and teaching, shared much information about the plant life of the park and the way it has been managed over the years.
She started by lending magnifying loupes to participants, explaining that a jeweler’s loupe at 10x would be best for field study. She demonstrated how to use them by bringing the loupe quite close to the face and resting it against the cheek to hold it near the eye. The object to study must be very near the bottom of the glass.

Regina pointed out which plants are native, non-native, and invasive. She shared her extensive knowledge about the plants and other species in the park. She pointed out and talked about over 50 plant species. We talked a bit about plant/bird interactions as well and discussed foraging and the possible risks to an inexperienced forager. Generally, foraging is not advisable in an ecosystem like Central Park, which would suffer greatly if thousands of visitors took up the practice. We encountered poison ivy (native) in the Loch. Regina explained that the Park has a policy of managing rather than eradicating this plant, which produces berries popular with 60 species of birds, as well as the urushiol oil that stimulates an allergic reaction in approximately half the people who come in contact with it. 

It was a very successful walk on a beautiful day in Central Park. Overall, we saw over 50 botanical species, eighteen birds, and several types of mammals, amphibians, reptiles, and insects.
