Requires DEP to establish "private wildlife habitat certification program"; creates affirmative defense against municipal nuisance ordinances for properties certified under the program.

This bill creates a state-certified program for private wildlife habitats in New Jersey. Property owners who establish habitats meeting DEP standards - using native plants and approved by certified entities like conservation groups or landscaping companies - can file a certificate with their municipality. Once filed, owners gain legal protection ("affirmative defense") against fines or penalties from local nuisance ordinances that might otherwise target natural habitat features. The certification lasts two years (with one renewal option) and requires inspections, with municipalities allowed to charge up to $25 for filing.
