EcoQuest Challenge Archive 2021
EcoQuests, part of the NYC EcoFlora Project, challenge New Yorkers to become citizen scientists and observe, study and help conserve the native plants and animals of the City, using iNaturalist, an easy-to-use mobile App.
The New York City EcoFlora project is made possible in part by the Institute of Museum and Library Services [MG-70-19-0057-19].
Pining for Pines - December 2021
Pine trees (Pinus spp.) are evergreen conifers that provide food and shelter for animals such as birds and small mammals. Pines are most diverse in the Northern Hemisphere, and their waxy, needle-shaped leaves help to minimize water loss for winter survival. New York City is home to five native and three introduced species of Pinus.
Several native species, such as P. echinata, P. rigida, and P. resinosa, grow well in sandy, nutrient-deficient soils. How many Pines can you find?
Help NYBG document as many Pines in New York City as possible by December 31.

Seek Seaside Goldenrod - November 2021
New York City has been historically home to 19 species of Goldenrod (Solidago), the iconic wildflower heralding cooler weather and the colorful fall foliage season. Mistakenly blamed for hay fever allergies, Goldenrod pollen is transported by insects, unlike wind-borne pollen of the real culprit, Ragweed (Ambrosia).
Seaside Goldenrod (Solidago sempervirens) inhabits coastal dunes, edges of salt marshes, and other maritime habitats, including around wharves and under piers and bridges. How many Seaside Goldenrod plants can you find?

Milkweeds and Monarchs - August 2021
Eastern Monarch Butterflies have declined by more than 80% over the past two decades. Although the U.S. Fish and Wildlife Service put Monarch Butterflies on the waiting list for Endangered Species Act listing in December 2020, that status does not provide protection for them or their habitat. Milkweed plants (Asclepias), the Monarch caterpillars’ only food source, have also declined.

Fern Foray - June 2021
Ferns are an evolutionary lineage of plants with vascular tissue like Conifers and Flowering Plants but that reproduce by spores like Mosses. In 1800 there were 60 indigenous Fern species in New York City. It is estimated that 30 percent of the original Fern flora is locally extinct and 20 percent of the remaining species are rare—primarily due to habitat loss.
Japanese Painted Fern is spreading from gardens and may be the first exotic Fern to naturalize in our area. How many Ferns can you find? Help NYBG document as many Ferns in New York City as possible by June 30, as well as determine whether Japanese Painted Fern is naturalized.
HOW DO I GET STARTED?
1. Download the iNaturalist app or register at iNaturalist.org.
2. Photograph Ferns anywhere in New York City. Observations showing the spore-producing structures (called sori and usually on the back of the leaf) are more likely to be identified by experts.

Check for Cherries - April 2021
Flowering Cherry trees (Prunus spp.) are synonymous with spring, but the clouds of pink and white flowers that appear in early April are produced by exotic species introduced in the 20th century, a few of which are emerging invasives. Our native species such as Black Cherry (Prunus serotina) and Beach Plum (Prunus maritima) bloom in May and June, well after the leaves have fully developed.
Help NYBG document as many Cherry trees in New York City as possible by April 30, especially the exotic species invading our woodlands.
HOW DO I GET STARTED?
1. Download the iNaturalist app or register at iNaturalist.org.

Browse Bryophytes - March 2021
Bryophytes are tiny plants classified as Mosses, Liverworts, and Hornworts. They were the first plants to colonize land and are still important pioneers, establishing an ecological foothold on boulders, barrens, and even buildings. Although they require water for reproduction, they can survive long droughts by going dormant. You can help us conduct the first inventory of New York City’s Bryophytes.
Photograph as many Bryophytes in New York City as possible by March 31!
HOW DO I GET STARTED?
1. Download the iNaturalist app or register at iNaturalist.org.

Salute Skunk Cabbage - February 2021
The remarkable Skunk Cabbage (Symplocarpus foetidus) is native to the northeast, occurring in swamps and wet woods. A member of the Arum family, most of the plant is underground, anchored by active, contracting roots that pull the buried stem downward. The flower clusters are thermogenic, producing enough heat to melt snow and enable the plant to bloom in late winter.
Photograph as much Skunk Cabbage in New York City as possible by February 28!
HOW DO I GET STARTED?
1. Download the iNaturalist app or register at iNaturalist.org.
2. Photograph Skunk Cabbage anywhere in New York City. Do not enter sensitive areas such as wetlands. Take photos from a distance.
