Land Conservation and Stewardship

FSM has helped pioneer landscape-scale forestland conservation through the development and implementation of conservation easements to sustain the ecological, economic, cultural, and recreational values of Maine’s forests. Since the organization was founded in 1984, FSM has helped conserve more than one million acres of forestland. FSM is responsible for ensuring all terms of our conservation easements are upheld forever.

Balance sheet

Fiscal Year: Aug 01 - Jul 31

SOURCE: IRS Form 990 info

The balance sheet gives a snapshot of the financial health of an organization at a particular point in time. An organization's total assets should generally exceed its total liabilities, or it cannot survive long, but the types of assets and liabilities must also be considered. For instance, an organization's current assets (cash, receivables, securities, etc.) should be sufficient to cover its current liabilities (payables, deferred revenue, current year loan, and note payments). Otherwise, the organization may face solvency problems. On the other hand, an organization whose cash and equivalents greatly exceed its current liabilities might not be putting its money to best use.
