Pennsylvania's State Parks house many green giants, some of which are found here in the Big Tree listing. The Big Tree program is a record of the largest trees found in Pennsylvania's State Parks. Each species is recognized, allowing for a wide variety of big tree champions, from the 125-foot tall Red Oak at Cook Forest State Park to the 15-foot tall Witchhazel at Clear Creek State Park.
The process begins with a nomination by a park visitor or employee. This nomination can be based upon visual inspection of the tree and some simple measurements. Once a tree is nominated for the Big Tree program, the score must be determined by a forester.
There are three criteria for determining the score of a tree. Circumference is a measurement taken in inches at 4.5 feet above the base of the tree (circumference at breast height). One point is given for each inch of circumference. The second measurement is height, and is the distance in a straight line from the ground to the highest point of the tree. One point is awarded for every foot of height. The final criterion, average crown spread, requires two measurements. The first measurement is taken at the widest point of crown spread, the second from the narrowest point. The two values are added and divided by two to give the average crown spread. One point is awarded for every four feet of average crown spread. The points awarded for the three criteria are then added to produce a final score, which is used to determine a tree's rank among other Pennsylvania State Park Big Trees.
When visiting a Pennsylvania State Park, keep an eye out for these giants. There are undoubtedly big trees that have yet to be found in Pennsylvania's State Parks. If you see a tree that might be eligible for the Big Tree program, write down the location and give it to the park manager to begin the nomination process.

| Laurel Highlands Hiking Trail |
One of the most exciting reasons to visit the park is for its scenery. Spring wildflowers dot the forest floor in early April followed by a vibrant green forest, as leaf out begins in late April. Mountain laurel blooms in June and rhododendron blooms in late June and early July. Come to the park in mid-October and witness fall color in all its glory. Winter is spectacular when the park is covered in a deep blanket of snow and the occasional great horned owl calls through the moon-lit forest. Explore Laurel Highlands Hiking Trail for more information.

The rich flora and fauna of Laurel Hill State Park make it a great place to watch wildlife year-round. The mixed-deciduous forest is dominated by oak, maple, cherry and poplar trees with an understory of witch hazel, serviceberry, rhododendron and mountain laurel. Although most of the park was timbered in the early 1900s, for unknown reasons the Hemlock Natural Area remains intact. The massive eastern hemlocks of this six-acre, old growth stand are now approaching the climax stage of succession. Explore Laurel Hill for more information.

| Moraine State Park |
Lake Arthur provides over forty miles of scenic shoreline. Its tributaries include Muddy Run, Big Run, Swamp Run, Bear Run and over 75 intermittent streams. Ranging from an average depth of 12 feet to about 36 feet deep near the dam, the shallow waters are home to a variety of warm water fish. Frogs, newts, turtles and water snakes prowl the edges of the lake. Avian anglers like the tall great blue heron, its short cousin the green-backed heron and the small belted kingfisher prey on minnows and fish fry, too small to be caught by human anglers. In the early spring, common loons stop at the lake on their migration to the far north. Osprey may be seen flying over Lake Arthur. Once extirpated from Western Pennsylvania, these "fish hawks" have been reintroduced to Moraine through a four-year hacking program begun in 1993. The first osprey pair to nest along Lake Arthur as a result of the reintroduction effort raised three young in 1996.
