Our Transformation from Fields to Woods

When you visit Baltimore Woods and hike through the woodland of tall, shady trees, it’s easy to imagine that Baltimore Woods has always been covered with trees. But not so long ago, it would have been more appropriate to call the preserve Baltimore Fields.

Before the European settlement, there was a mix of open land and young forest across our region. These habitats grew up after Native Americans burned woods to improve hunting and clear land for farming. Unchecked wildfires and storms leveled forested lands, and large herbivores kept areas open by browsing the regrowth. These influences gave rise to expanses of grassland as well as large areas of densely-regrown trees and shrubs.

It is likely that some of the area that we now call Baltimore Woods was forested until the late 1700s, when the first Europeans settled in Marcellus and began to transform the land. With axes, fire, and other tools, the woodland was soon cleared to make way for farming and timber to build the growing nation.

For the nearly two centuries, what we now call Baltimore Woods was mostly farmland. And by the 1920s, when agriculture was at its peak in Central New York, less than one quarter of the preserve was covered in trees. Even in those areas, some logging was probably taking place.

A series of aerial photos, beginning in 1938, tells the story of how the land changed during the 20th century. The 1938 photo shows the extent to which the land was worked, with all but the steepest areas either tilled or pastured.

In the 1950s, the farming began to be phased out of the less-productive areas, and first signs of brush start to slowly creep in.

By the mid-1960s, large sections of the property are clearly becoming brushy pastures and some of the wooded sections have started to expand.

1960's
By the time that ‘the Woods’ had been protected in 1972, most of the farming had stopped and the reforestation was allowed to happen unchecked; many of the brushy fields had started to become young forest. But a hand drawn map from the early 1980s still shows large areas as open land. The period between mid-1980s and mid-1990s is probably when Baltimore Woods held its greatest diversity of habitats and provided a home to the widest variety of species, with its good mix of open field, shrub fields, young forest, and older forest.

1980's

By the mid-1990s, the open areas were beginning to disappear as the brushy areas continued to grow into young forest, and the young forest into older forest.  As open areas declined, so did the plants and animals that called them home. This loss did not go unnoticed.

1995
In the early 2000s, the Boundary Trail was constructed, partly to provide better access to the remaining open areas so a tractor, equipped with a brush mower, could start to halt the loss of habitat. In the mid-2000s, aggressive action was taken, and a volunteer with a bulldozer cleared acres of brush around the remaining meadows; the vegetation removed was mostly exotic invasive species.

2006
Today we continue our work to protect, restore, and expand the open meadow areas. Our new land stewardship plan will help guide us to maintain a good diversity of species, both plants and animals, that call Baltimore Woods home.

So, next time you visit the Woods, stop and take a moment to think that once, and not all that long ago, most of this was open land and only a little bit of the Woods was wooded. 





Why it’s called Baltimore Woods:

In the 19th century, most of the 180 acres that we now know as Baltimore Woods Nature Preserve was working farmland. At that time, the majority of farmers in this area marketed their cattle in New York City. It seems that one of those farmers, however, had a falling out with his NYC middlemen and decided to send his cattle to market in Baltimore instead. So, he purchased and worked a piece of property located close to the railroad line that went to Baltimore. In fact, remnants of that now-defunct train line can still be found on the east side of Lee Mulroy Road. It's funny which names "stick" sometimes: the feisty farmer's former lands and the brook that meanders through them now carry not his name, but the exotic and evocative name of distant "Baltimore."

The Baltimore Woods area has been farmed for at least 150 years with the peak of agriculture coming sometime between 1900 and 1920. At that time only about 30 acres of woodland remained in what is now Baltimore Woods, including the steepest parts of the south slope of Baltimore Valley and a small block of hardwoods at the southwest corner of the Parson's Parcel.

When agriculture began to be phased out the 1950s, in most of Baltimore Woods plant succession slowly took over adding acres of pioneer forests, shrublands and scattered herbaceous clearings.

Today, the average visitor to Baltimore Woods would not recognize the differences between the more recent forests and the "original" forest tracts. However, analysis of these forests based on species and DBH (trunk Diameter at Breast Height) reveals differences which provide educational opportunity and suggest management needs.

Baltimore Woods Becomes a Nature Preserve

In the mid-1960s a committee of representatives from local nature and environmental groups met to discuss the preservation of natural areas in Onondaga County. Baltimore Woods was one of a couple of dozen natural areas deemed worthy of preservation.

In 1972, people from this group formed Save the County to begin the process of acquiring and setting aside a number of these areas for preservation.

An Uninvited Guest

When you visit Baltimore Woods you may not realize that one of the dominant shrubs in the Woods is an unwanted foreign invader.
Tartarian honeysuckle (Lonicera tatarica), a bush honeysuckle,
crowds and shades out native plant  pollinators.
Quick facts:
  • Eastern Asia Eurasia
  • Introduced to the US as an ornamental plant in the mid 1700’s it was also planted  for wildlife cover and for soil erosion control.
  • Shaggy grayish brown
  • Naturalized in most of the US
  • Reduces biodiversity
  • The seeds are distributed to new areas in bird droppings
