The Nature Conservancy of Canada is thousands of dollars short, and running out of time, to protect a stretch of beach along Nova Scotia's south shore.

Part of the nearly 150 hectares of land in Port Joli was donated, but most of it was purchased.

The project cost $600,000 and the conservancy is $30,000 short.

Andrew Holland, spokesman for the Nature Conservancy of Canada, said they have less than five weeks to come up with the money.

"We want to see these dollars invested in this natural area in Nova Scotia. We need a golden opportunity here to build on our land assemblage and protect a lot of the duck population in that area and we're hopeful that we'll reach the deadline," he said.

"We have every confidence we will, there has been instances where that hasn't taken place and that's why there's some urgency here."

To date, the Nature Conservancy of Canada has protected over 10,000 hectares of land in Nova Scotia.
