INTRODUCTION 



The Allegany State Park is located in the southern 

 part of Cattaraugus county, south of the great bend of 

 the Allegheny river, and bounded on the east by the 

 valley of the Tunungwant creek, which flows northward 

 from Pennsylvania into the Allegheny at a point about 

 ten miles west of Olean. The accompanying sketch map 

 (figure 2) of western New York indicates the location 

 of the park area (heavily shaded) and the adjacent 

 Allegheny and Tunungwant valleys (lightly shaded), with 

 reference to the principal political and geographical 

 features of the region. The larger map (figure 34) 

 indicates the location of the streams and localities men- 

 tioned in the following pages. The flora of these valleys 

 has been included in this survey largely for the contrast 

 it forms with the flora of the uplands of the park area 

 proper. 



The location of the park area is along the northwest 

 rim of the great Appalachian plateau, but outside of the 

 southern limits of the ice sheet of the glacial period. The 

 southern limit of the glaciated region forms a great 

 curve around the western and northern sides of the
