FLORA OF LONG ISGAND, NEW york 
Project 1. Vegetation of Long Island, New York 
Scope: 
A study of the vegetation types of the island and the factors of 
their environment. 
Status: 
Montauk and other grasslands reported upon or ready for pub- 
lication. 
Forests: Not yet completed. 
Salt marshes: Not yet completed. 
Plans: 
To complete field work and laboratory studies on 
a. Forests of Long Island. 
1. Description of types, and successional trends. 
2. Completion of study of soil potentialities of the island 
as related to production of forest and agricultural 
crops. 
3. Securing data on relation of stages of succession as 
correlated with soil fertility, humus accumulation, 
and hydrogen-ion concentration ; the time relation of 
these; the effects of vegetation types on the site. 
4. Continuing study of climatic factors involved, es- 
pecially evaporation and wind movement and their 
effect upon plant transpiration and plant distribu- 
tion. 
b. Salt marshes of Long Island. 
1. Continuing work on distribution of vegetation on the 
drained and undrained salt marshes, particularly 
with reference to availability of salt marsh mucks 
for agricultural purposes. The relation of  salt- 
tolerant species to varying degrees of salinity in 
tidal creeks and marshes.
