April EcoQuest

Map Maple

Maple (Acer spp.) is an ecologically and economically important genus of trees that have distinctive palmate leaves and winged fruits. There are at least 12 species of maple found in New York City, including Norway maple (A. platanoides), a common street tree; sugar maple (A. saccharum), the state tree of New York; and boxelder (A. negundo), the only North American maple with compound leaves. In early spring, many species produce flowers while the tree is still leafless. How many maples can you find?

March EcoQuest

Browse Bryophtes

Bryophytes are small, non-vascular, spore-bearing plants which include mosses, liverworts, and hornworts. They are pioneers of barren surfaces such as rocks, tree trunks, and pavement, and play essential roles in nutrient cycling, soil formation, and water retention. An inventory of the bryophytes of New York City has never been published, but there are currently 85 species with Research Grade observations available on iNaturalist.

Your observations will help to further our understanding of the variety and abundance of bryophytes in our city!

February EcoQuest

Behold Bark, Buds, and Berries

Clockwise from top left: American Hornbeam (Carpinus caroliniana) bark; Japanese Angelica Tree (Aralia elata) stem; Boxelder (Acer negundo) bud; Swamp Rose (Rosa palustris) fruits; Striped Wintergreen (Chimaphila maculata) leaves.

February is a great month to refine your winter botany skills by learning to recognize important dormant-season plant characteristics such as bark, buds, and persistent flower and fruit structures.
Previous winter-month EcoQuest Challenges provide many examples of common plants that can be identified in winter, representing diverse groups of native and invasive species, including cryptogams and gymnosperms as well as flowering plants (grasses, vines, shrubs, and trees).

How many species can you find this February?

January EcoQuest

Look for Lichens


Clockwise from top left: British Soldier Lichen (Cladonia cristatella), Common Greenshield Lichen (Flavoparmelia caperata), Cobblestone Lichen (Acarospora sp.), Bare-bottom Sunburst Lichen (Xanthomendoza weberi).

Lichens are unique organisms formed by a symbiotic relationship between fungi and algae or cyanobacteria. The fungus provides a structure and protection, while its partner contributes energy through photosynthesis. Formerly scarce in NYC due to air pollution, improvements over the last 50 years have spurred a resurgence of lichens in the city. On iNaturalist there are over 2000 research grade observations of 88 species of lichen in NYC, and thousands more not fully identified. Learn more about the lichens of New York City and help contribute to our knowledge on urban lichens!

December EcoQuest

Pursue Parthenocissus


Clockwise from top left: Parthenocissus quinquefolia (Virginia Creeper); P. tricuspidata (Japanese Ivy); tendrils with adhesive pads found in Virginia Creeper and Japanese Ivy; P. inserta (Thicket Creeper).

Parthenocissus is a genus of tendrillate vines in the grape family, with three species found in New York City. Among them are the native, five-leaved Virginia Creeper (P. quinquefolia) and the introduced, trifoliate Japanese Ivy or Boston Ivy (P. tricuspidata), both capable of climbing smooth surfaces thanks to adhesive pads on their tendrils. The third species, Thicket Creeper (P. inserta), is less commonly observed, possibly due to misidentification as P. quinquefolia. Can you spot all three species this month?

Great Tree Search 2023

Great Tree Search

For the first time since 1985, the Great Tree Search has been launched by NYC Parks to designate a set of Great Trees across the city. Anyone can nominate a tree based on its historical, cultural, or botanical significance. To celebrate this initiative, this month's EcoQuest is highlighting rare or threatened tree species that qualify as “botanically significant”, such as Yellow Birch (Betula alleghaniensis), Butternut (Juglans cinerea) (pictured above), and the critically endangered American Chestnut (Castanea dentata). Check out the project page on iNaturalist to learn more about NYC's rare tree species, and remember to submit your nominations for the Great Tree Search!

October EcoQuest

Goldenrods and Galls

The yellow blooms of Goldenrod are a familiar sight to many New Yorkers this time of year. However, there is more to these autumn beauties than meets the eye. Goldenrods (Solidago and Euthamia spp.) are host to a wide variety of gall-forming insects, who create homes for their offspring by inducing abnormal growth in the tissues of plants. This month we are asking participants to document Goldenrod species as well as to look carefully to find and to photograph any galls they might be hosting.


For resources and a guide to Goldenrod Galls in the Northeast, please refer to this wonderful post made by user @ddennism :

September EcoFlora Virtual Lecture and community feedback opportunity

Plants Can Help Make the NY–NJ Harbor Estuary Fishable and Swimmable!

Robert Pirani, Program Director, New York–New Jersey Harbor & Estuary Program at the Hudson River Foundation

Tuesday, September 26, 5:00PM EST

REGISTER HERE

The New York–New Jersey Harbor Estuary is the largest public resource in the nation’s greatest city. Conservation and management of its flora can help make its waters fishable and swimmable, and help ensure that the estuary’s many benefits are available to people throughout the region. Rob Pirani, Program Director of the New York–New Jersey Harbor & Estuary Program at the Hudson River Foundation, will talk about some of the opportunities and challenges.


Robert Pirani is the program director for the New York–New Jersey Harbor & Estuary Program at the Hudson River Foundation. HEP is a collaboration of government, scientists and the civic sector that helps protect, restore, and provide access to the Hudson River Estuary. It is one of 28 such programs around the country authorized under the Clean Water Act.

September EcoQuest

Spot and Squash September

Since it was first spotted in New York City in 2020, the Spotted Lanternfly (Lycorma delicatula) has quickly multiplied and become a significant threat to many economically and culturally significant plants such as grapevines (Vitis spp.), stone fruits (Prunus spp.), and Maple (Acer spp.). Adults will begin laying egg masses in September, which will overwinter to hatch next spring. You can help by documenting where these egg masses are located, and by destroying them to prevent further infestation.


Use this guide to learn about how to remove and destroy egg masses:
