2024 NYRP Tree Giveaway

The annual New York Restoration Project Tree Giveaway begins distribution on Saturday, April 13th, a little less than 6 weeks away. It runs for four weeks, ending on Sunday, May 12th.

Advance registration is mandatory. You select your preferred species when you register. Note that each location will only have 6-8 species. Some locations, especially smaller sites, may be “sold out” of some species. So, check the locations you can get to, confirm you can do it on their giveaway dates, and select from the species available at those sites.

Consider the mature size, after 30 or more years of growth, of each species. There are two lists below: one for smaller-medium sized shrubs and trees that max out at no more than around 50′ high and 30′ wide; the other for the larger trees that will grow too large for most urban yards. These sizes do not take into consideration existing vegetation, outdoor structures, etc. Your conditions will vary!

Salix discolor, pussy willow

I’ve highlighted the 12 species that are NEW for 2024. The 6 species that aren’t available this year are crossed out.

Shrubs and Smaller Trees

Larger Trees

Brooklyn Locations

There are 8, two more than last year, Brooklyn pickup sites.

Sunday, May 22nd 6th, I will be hosting and facilitating a workshop on gardening for habitat with native plants in my home garden. The workshop is from 12noon to 2pm. Space is limited, so please register at the Eventbrite link below.

Learn how to garden with native plants to create wildlife habitat, even in small urban gardens. In this interactive garden tour and workshop, Chris will use his garden to highlight the importance of native plants for sustaining urban wildlife, and how to create and maintain a garden for its ecological value. With nearly 200 NYC-native plant species, and over 400 documented insect visitors, you are sure to learn something new and find inspiration for improving habitat wherever you garden.

Presented by Chris Kreussling. Chris is an urban naturalist and advocate for urban habitat gardening with native plants. He has led numerous native plant and pollinator walks and workshops, for NYC Wildflower Week, Wave Hill, the High Line, and others. His garden is a registered habitat with the National Wildlife Federation, Xerces Pollinator Society, and other organizations. He’s documented this ongoing transformation on his gardening blog, Flatbush Gardener and on Twitter as @xrisfg.

Eristalis arbustorum (left) and and Syritta pipiens (right), thick-legged fly, on NOID Lamiaceae, 6&B Community Garden, East VIllage, Manhattan, July 2012

It’s a busy season for me this Spring! NEXT WEEK is New York City NYC’s GreenThumb community gardening program annual conference, known as GrowTogether:

Part 2 of the GreenThumb GrowTogether conference will be hosted in-person in community gardens in all five boroughs in celebration of Earth Week. Join us for workshops about growing food, healthy eating, native pollinators, flower arrangement, planting seeds, screen printing garden swag, volunteer projects, and more. All the activities are free and open to the public!

… The theme of this year’s GrowTogether is “Deeply Rooted: Growing Community Connections.” Community gardeners from across New York City have been gathering at the GrowTogether conference each spring since 1984 to celebrate the start of the garden season with a day of learning, networking, and reconnecting with friends. – Ibid.

38th Annual GreenThumb GrowTogether Conference Part 2 Conference Guide

As noted above, all GrowTogether workshops are open to the public. Please register, as some workshops have limited capacity.

This is my first time participating in GrowTogether. I’ll be giving two different workshops on how to use iNaturalist, Friday in Brooklyn, and Saturday on Staten Island.

Using iNaturalist for Community Gardens and Gardeners

Friday, April 22
Time: 11:00 a.m. – 1:00 p.m.
(Rain Date: Saturday, April 23, same time)
Location: Vernon Cases Community Garden, 42 Vernon Avenue, Bedford-Stuyvesant, Brooklyn
Description:

iNaturalist is a community/citizen science platform where anyone can record their observations – photos or audio recordings – of any living thing anywhere in the world. Community gardeners and visitors can use iNaturalist to document and keep records about their gardens, such as flowering and fruiting times; identify and keep track of common weeds; and identify insect visitors, whether pests, predators, or pollinators.

In this workshop, we will use iNaturalist “in the field” to make observations of plants and insects and upload them to iNaturalist, creating a record of the biodiversity in a community garden. If you have access to a smartphone, please download the iNaturalist app in advance and bring it to the workshop!

Meet and Greet New York City’s Native Pollinators

Saturday, April 23
Time: 11:00 a.m. – 1:00 p.m.
(Rain Date: Sunday, April 24, same time)
Location: Hill Street Community Garden, Staten Island
Description:

New York City is home to hundreds of species of pollinating insects. While butterflies and bumblebees are easily-spotted inhabitants of our community gardens, meet a few of New York City’s lesser known pollinators—including wasps, flower flies, and specialist bees— during this workshop with Sarah Ward from National Wildlife Federation and Chris Keussling (aka Flatbush Gardener). During a walk through the garden, participants will learn tips and tricks for observing pollinators and welcoming them into our gardens. Participants will also learn how to use the community science app iNaturalist to identify pollinators and contribute valuable data about pollinators in New York City.

Torrey Lecture, Wednesday March 30

2022-04-07: The recording is online on the Torrey Botanical Society YouTube channel.


I am proud to announce that I will be co-presenting, with Zihao Wang, a Lecture of the Torrey Botanical Society on Wednesday March 30 at 6pm. The title of the talk is “City Nature Challenge (CNC) 2022: For Plant-lovers and Botanists Alike.”

Screenshot of top 30 Species Observed during NYC's CNC 2021

Note that the information we present will be applicable to iNaturalist users and City Nature Challenge observers and identifiers anywhere in the world! So, whereever you are, please join us if you can.

Abstract

Unlike most other citizen science platforms, iNaturalist allows anyone to record their observations of any living thing anywhere in the world. As it approaches 100 million Observations worldwide, it has become increasingly important to botany and other biological sciences. City Nature Challenge, based on iNaturalist, engages community members in cities and urbanized areas around the world to make observations, and provides opportunities for taxonomic experts to identify them, all over the world. Last year over 400 cities participated, with over 50,000 people documenting over 45,000 species with over 1.2 million observations, the largest bioblitz in the world. In this Torrey Talk, two iNaturalist experts will show how you can participate in iNaturalist and this year’s upcoming City Nature Challenge.

Registration

Date: 2022-03-30
Time: 6pm EDT (GMT-04:00)
Duration: 1 hour
Registration: Zoom

The talk will be recorded and made available on the Torrey YouTube channel sometime after the event. Please subscribe to our channel and enable notifications so you get updated when we publish new recordings!

I’m pleased to announce that Saturday, September 25th, I will be leading two iNaturalist Workshops “in the field” at The High Line. This is one of several workshops, and many other events, they have scheduled for Insectageddon, which runs from 3-6pm that Saturday afternoon.

Self-Portrait of an iNaturalist as an old man

I’ll be doing two walks:

  • 3:15-4:15 pm
  • 4:45-5:45 pm

When not out on one of the walks, I’ll have a table in The High Line’s Chelsea Market Passage, between 15th and 16th Streets. Please sign up there for one of the two workshops, as space will be limited. Each walk will start out from that location.

iNaturalist Workshop
Hosted by Chris Kreussling, aka “Flatbush Gardener”
Join Chris Kreussling for a walk on the High Line to explore plant and insect interactions and learn about the citizen scientist observation gathering tool iNaturalist. Tours begin at 3:30 and 4:45; please sign up upon arrival at Chris’s table in Chelsea Market Passage. Chris is a Brooklyn naturalist and gardener specializing in gardening with native plants to create habitat for pollinators and other invertebrates.

Visiting the High Line
