Hello ENTS,

I am working my way through Long Island parks and preserves in search of
great trees. As you may have guessed these are in short supply here.

Having been extensively populated since the 1850's most of the land was
cleared for buildings or farms. The farms were built on the Hempstead
Plains, a natural prairie of some 60,000 acres.

Two exceptions seem to have been the 'Pine Barrens', an extensive dwarf
pitch pine forest, whose underlying ground would not support crops, and the
north shore area of Great Neck and Huntington.

In 1947 wholesale development began on the former farmland. Small trees
were planted, or allowed to grow, and make up the majority of the trees in
Nassau County(60~years).

The north shore seems to have always attracted wealthy landholders who
held on to what they had, including trees. This culminated in the building
of great private estates between 1900-1930's. Trees were spared, and in
fact, added to with exotics. Since that time most of the estates have been
aquired by various government bodies through attrition and are now parks and

Many others have been razed and their lands developed upon- the trees
