Twenty years in the New Jersey Meadowlands

For the last twenty years our scientists & their associates have studied the New Jersey Meadowlands, an important urban wetland. Their goal is to understand through this case study how some organisms thrive in urban areas, and others do not, how land-use & climate change alter biodiversity, and how we can best protect the viability of urban habitats and their diverse denizens without prohibitively large expense.

  • The New Jersey Meadowlands: An Overview

    In 1999, Hudsonia was called in to join a group of experts reviewing the environmental assessment documents for a project that proposed filling 80 hectares of the most extensive remaining wetland in the Meadowlands. The more Erik Kiviat and his collaborator Kristi MacDonald studied the region, in literature and in the field, the more complexity they found in the supposedly simple and unimportant urban habitats, and we have continued the study with the support of our donors ever since. We are excited to share what we have found with you.

  • The Upper Penhorn Marsh

    The Upper Penhorn Marsh is a brilliant example of the conservation importance of that which is already there. Sustaining itself in a highly altered landscape, this unusual mossy ecosystem is bordered by the New Jersey Turnpike & a railroad, covers 170 acres and supports rare species including a substantial breeding population of the newly described Atlantic Coast leopard frog. Ecologists can learn a great deal from it. Please help us protect it.

  • Two Urban Gems under Threat

    This is a tale of two city greenspaces, one high and one low, one a park and one privately owned, both supporting concentrations of rare habitats and species, and both being destroyed by unnecessary actions.

  • Alice in Meadowlands

    An essay written by Erik Kiviat about half way through this study, evoking the many species living among the abandoned industrial archipelagos, and framing a number of important questions about ecological conservation and restoration.

  • Least tern

    The Birds of the Meadowlands

    Here is a list of the surprising number of birds, including known breeding populations of endangered species, like this least tern, and about 150 of conservation concern that can be found in the Meadowlands.
