The Rensselaer Plateau is a small plateau located in the central portion of Rensselaer County, New York; it generally encompasses significant parts of the towns of Berlin, Stephentown, Sand Lake, Poestenkill, and Grafton, along with small sections of several other nearby towns.
 Many glacial lakes, including Big Bowman Pond, Little Bowman Pond, Round Pond and Spring Lake are located on the plateau.
 Elevations on the plateau range from 1,000 to 2,000 feet (305 to 610 meters) above sea level.
 Vegetation on the plateau is more similar to that found in the Adirondack Mountains to the northwest, with abundant Eastern White Pine, Eastern Hemlock, Red Spruce, and Balsam Fir, along with more limited occurrences of Red Pine and Tamarack.
 While most to all of the plateau was logged late in the 19th Century and early in the 20th Century, little farming was undertaken afterwards due to extremely poor and rocky soils, allowing much of the forest to regenerate.
Big Bowman Pond is a small glacial lake in the Taborton section of the Town of Sand Lake, Rensselaer County, New York, United States.
 The lake is located on a geologic formation known as the Rensselaer Plateau.
Round Pond is a small glacial lake in the Town of Berlin, Rensselaer County, New York, United States.

Spruce sawflies are various sawfly species found in North America that attack spruce.
 There are multiple species of sawflies, including, European spruce sawfly, yellow-headed spruce sawfly, green-headed spruce sawfly, little spruce sawfly, and spruce webspinning sawfly.
 Each kind of sawfly attack particular parts of the spruce during different times of the year.
 These insects first begin feasting, or attacking, spruce as [larvae] and continue until they are fully grown.
The blue spruce, green spruce, white spruce, Colorado spruce, or Colorado blue spruce, with the scientific name Picea pungens, is a species of spruce tree.
 It is native to the Rocky Mountains of the United States.
 Its natural range extends from northern New Mexico through Colorado and Utah to Wyoming and into far southwest Montana, but it has been widely introduced elsewhere and is used as an ornamental tree in many places far beyond its native range.
 The blue spruce has blue coloured needles and is a coniferous tree.
Little Bowman Pond is a small glacial lake in the Taborton section of the Town of Sand Lake, Rensselaer County, New York, United States.
 The lake is located on a geologic formation known as the Rensselaer Plateau.
Picea rubens, commonly known as red spruce, is a species of spruce native to eastern North America, ranging from eastern Quebec to Nova Scotia, and from New England south in the Adirondack Mountains and Appalachians to western North Carolina.
Picea glauca, the white spruce, is a species of spruce native to the northern temperate and boreal forests in North America.
 "Picea glauca" was originally native from central Alaska all through the east, across southern/central Canada to the Avalon Peninsula in Newfoundland.
 It now has become naturalized southward into the far northern United States border states like Montana, Minnesota, Wisconsin, Michigan, Vermont, New Hampshire and Maine; there is also an isolated population in the Black Hills of South Dakota and Wyoming.
 It is also known as Canadian spruce, skunk spruce, cat spruce, Black Hills spruce, western white spruce, Alberta white spruce, and Porsild spruce.
Cinara pilicornis, the spruce shoot aphid or brown spruce shoot aphid, is an aphid species in the genus "Cinara" found on Norway spruce ("Picea abies") and Sitka spruce ("Picea sitchensis").
 It is a quite large aphid species with a plump, dull brown body.
 It seems to have little effect on the tree.
 It is a European species but it has also been reported in spruce forests in New Zealand, together with the spruce aphid ("Elatobium abietinum").
