Natural Heritage

This beautiful old forest is very biodiverse. Many of the trees are truly majestic.  Like most forests on steep north-facing slopes, this one has a significant component of white pine and hemlock, but Slim Jim Woods is dominated by hardwoods: oaks, hickories and maples. The biggest, tallest trees seem to be at the bottom of the slope; whether they are older or found better conditions there is not clear.

The slope is steep, gravelly and somewhat unstable. On steep slopes such as this one, the downslope movement of soil, water, solutes and organic matter, leads to a general pattern of increasing soil pH, soil fertility, and species diversity from top to bottom of the slope. One can readily observe the change in species diversity on this slope. The base is very species-rich, especially in herbaceous species, which are sparser and less diverse higher up.
