SUMMARY:CNC Observation with DC Master Naturalists
DESCRIPTION:(VA) (Capital Nature) Join DC Master Naturalists and Capital Nature for our annual City Nature Challenge observation at Fort Dupont Park. Fort Dupont hosts some of DC’s most abundant biodiversity of birds\, fungi\, and plants (as well as invasive plant challenges)\, but they often go unnoticed. Help us put this green gem on the map while you enjoy a restorative walk with naturalists. The walk will be led by wildlife biologist Carrie Seltzer from iNaturalist. \nThe late afternoon starting time will increase our opportunities to hear local and migratory birds! \n

SUMMARY:Meet Your Neighborhood Arborist
DESCRIPTION:(DC) (Capital Nature) Did you know that every neighborhood in the District has a city Arborist who manages its public trees? Join us for a discussion with Aaron Rowe\, the DC Arborist who looks out for the street and park trees in Cleveland Park and Woodley Park\, two of Northwest DC’s greenest neighborhoods. Aaron will give an overview of the city’s Urban Forestry Division and his work as a public Arborist\, then join Capital Nature’s co-founder Stella Tarnay for a discussion. We’ll talk about the health of the area’s trees\, how the city is protecting them\, the challenges they are facing\, and how residents can contribute to the health of our public canopy. \nThis is the first in a three-part series on trees and their care hosted by Cleveland Park Library in collaboration with Capital Nature.
