More than 100 species of birds, some 20 species of mammals, and over 300 species of trees, shrubs, and wildflowers have been observed in Jockey Hollow at various times of the year. A walk over the Nature Trail (pp. 20, 35), which begins and ends at the Picnic Area (No. 10), affords opportunity to enjoy seeing many such elements of the park landscape. The area is a wildlife sanctuary, however, and visitors are reminded that disturbance of its natural features is prohibited by law (pp. 43 -44). NO. 12. OLD CAMP ROAD, 1779-80. Almost opposite the Picnic Area (No. 10), intersecting with the east side of the Jockey Hollow Road, is what has long been known as the Old Camp Road (p. 20). This leads across Mount Kemble to the old Basking Ridge Road, now Mount Kemble Avenue (U. S. Route 202), and to the site of Jacob Larzeleer’s Tavern, where Brig. Gen. John Stark made his quarters in 1779-80. Part of the road may have been built as the result of orders issued to Stark’s and the New York Brigades, on April 25, 1780, to “open a Road between the two encampments.” NO. 13. FIRST MARYLAND BRIGADE CAMP, 1779-80. About one-sixth of a mile southwest of the Picnic Area (No. 10), on the same side of the Jockey Hollow Road and parallel to it, is the campsite occupied in 1779-80 by the 1st Maryland Brigade under Brig. Gen. William Smallwood. In this brigade were the 1st, 3d, 5th, and 7th Maryland Regiments, with a combined total enlistment, in December 1779, of 1,416 men. The official uniform of these troops was blue, faced with red; the buttons and linings, white. About the middle of May 1780, following the departure of the 1st Maryland Brigade on April 17 preceding, soldiers of the Connecticut Line moved into the log huts erected on this site (p. 41). NO. 14. SECOND MARYLAND BRIGADE CAMP, 1779-80. About three-tenths of a mile southwest of the Picnic Area (No. 10), paralleling the opposite side of the Jockey Hollow Road, is the campsite occupied in 1779-80 by the 2d Maryland Brigade under Brig. Gen. Mordecai Gist. In this brigade were the 2d, 4th, and 6th Maryland Regiments, and Hall’s Delaware Regiment, with a combined total enlistment, in December 1779, of 1,497 men. The official uniform of these troops was the same as that of the 1st Maryland Brigade. About the middle of May 1780, following the departure of the 2d Maryland Brigade on April 17 preceding, soldiers of the Connecticut Line moved into the log huts erected on this site (p. 41). NO. 15. BETTIN OAK AND FORT HILL.
