A biological resources study of the Arrowhead Springs Resort property was conducted in 1998 and again in 2004.   The results are summarized below:

Habitats:

	Traverse Range Coastal Sage Scrub
	Traverse Range Upper Chaparral
	Traverse Range Lower Chaparral
	Ruderal Annual grassland
	White Alder Riparian Woodland
	Freshwater marsh
	Freshwater and Mineral Seeps and Springs

On higher slopes above the property area are Mixed Hardwood and Yellow Pine Forests.

The vegetation throughout the majority of the 1,916 acres consists primarily of native species, including mountain laurel, cactus, and wild brush. Throughout the developed portion, mature evergreen trees, oak, eucalyptus, five species of palms, lemon, orange, apple, peach, grapefruit, apricot, and olive trees dominate the landscape, as well as lush lawns and flowering plants. 

Wildlife include rabbits, skunk, bobcat, deer, mountain lion, bear, coyote, snakes, raptors, morning doves, crows, heron, ducks, kingfisher, woodpecker, owl, and squirrels.

Development at Arrowhead Springs will include the addition of new ponds, a public Botanical Garden, expansion of Lake Vonette, and vineyards. These improvements will provide new habitats for more flora and auna. In addition, 1,400 acres (over 70%) of the property will be preserved as natural landscape and watershed.
