Working for Forest Health Written Collaboratively by Ted Martello, Mary Jane Shanks, and Jim Curtis Council Board Members If you are one who regularly enjoys hiking through the woods and meadows at Oregon Ridge Park, you may be asking yourself, “What the heck is going on?” ere are trees disappearing, pipes stacked high, new roadways popping up, areas of a meadow turning to stone, some trails closing, and new plants taking over in places where trees once grew. Just what is happening at Oregon Ridge? e answer is much! You may know from reading previous issues of the Trailblazer that a major project has begun in Oregon Ridge’s forest interior — the expansion of the Columbia Gas pipeline. You may not know that a County led tree-thinning project to promote the regeneration of oak trees is also occurring simultaneously with the pipeline activities. Together these two projects have created a classic scenario of e Good, e Bad and e Ugly at Oregon Ridge. Let’s start with e Good. Both projects were launched with good intentions to help either humans or populations of native species, both plant and animal. e pipeline expansion will bring better services to many Maryland citizens. e tree thinning is a result of a 2007 forest assessment that showed the oak tree population disappearing from the forest due in large part to overcrowding by other, less beneficial trees. inning will hopefully allow oak regeneration. As often happens, two nasty cousins, e Bad and e Ugly, are shadowing e Good. e Bad is that both projects have created problems for Oregon Ridge. e pipeline comes with some expected problems, several of which are temporary: the loss of many healthy, mature trees, inconvenience to hikers (continued on page 6)

We were taking care of the rooster, and he ended up escaping and rummaging through the woods. It ended up taking me, another ridge runner, and two other staff members to catch him! I never thought it’d take so much energy to outsmart a rooster!
