Environmental Education

The Wetlands Institute accomplishes its mission of education through a multi-faceted approach. Over 12,000 children visit from schools in New Jersey and neighboring states in the spring and fall. Distance-learning programs provide an opportunity to interact with students around the country while local schools are visited with hands-on programs. During the summer season, nature classes reach children in grades pre-K through 6. Our Junior Naturalist and Intern-for-a-Week programs give senior high students a chance to gain personal insight into the world of the field biologist and the environmental educator. Visitors to the Institute are shown a short film "Secrets of the Salt Marsh" followed by a visit to exhibits and aquarium that reveal those secrets. A guide takes visitors on a "salt marsh safari" on the marsh and pier extending over a salt water channel.

Balance sheet

Fiscal Year: Jan 01 - Dec 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.
