The Natural Areas Association is the only national, non-profit membership organization that is dedicated to the support and advancement of the community of natural areas professionals.

Together, we envision a world where science-based conservation is the bedrock of protecting the beauty and wonder of nature.

Our members work to protect and restore natural areas, ecosystems and landscapes, and include natural lands managers, natural resource managers, land trust staff and volunteers, biologists, ecologists, researchers, policy specialists, educators, students, and anyone with an active interest in environmental conservation and natural areas stewardship.

We:

  • Support, nurture and advance the community of NA professionals
  • Advance natural area conservation through access to the latest research findings, as well as emerging management techniques and conservation practices
  • Promote an understanding and appreciation of natural areas, and the people who work to steward them
  • Advocate for legislation that supports and funds initiatives important to natural areas
  • Reflect the consensus of natural areas professionals through statements of policy

Much of the coastal sage scrub habitat in Southern California that existed prior to European settlement has been developed for human uses. Over the past two to three decades, public agencies and land conservation organizations have worked to acquire some of the remaining lands for preservation. Many of these lands are degraded by past intensive livestock grazing, farming, and frequent fires, and the native flora has been replaced by weedy, exotic annual grasses and forbs, mostly of Mediterranean origin.

Land management practices, invasive species expansion, and changes in the fire regime greatly impact the distribution of native plants in natural areas. Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis), a keystone species in the Great Basin, has seen a 50% reduction in its distribution. For many dryland species, reestablishment efforts have focused on direct seeding but achieved only minor success due to irregular seed germination and poor survival.

As species' geographic ranges and ecosystem functions are altered in response to climate change, there is a need to integrate biodiversity conservation approaches that promote natural adaptation into land use planning. Successful conservation will need to embrace multiple climate adaptation approaches, but to date they have not been conveyed in an integrated way to help support immediate conservation planning and action in the face of inherent spatial uncertainty about future conditions.

Botanical capacity plays a fundamental role in solving the grand challenges of the next century, including climate change, sustainability, food security, preservation of ecosystem services, conservation of threatened species, and control of invasive species. Yet critical components of botanical education, research, and management are lacking across government, academic, and private sectors.

Seeds of Success (SOS) is a national native seed collection program, led by the US Department of Interior Bureau of Land Management in partnership with numerous federal agencies and nonfederal organizations. The mission of the SOS is to collect wildland native seed for long-term germplasm conservation and for use in seed research, development of native plant materials, and ecosystem restoration. Each year about 50 SOS teams are stationed across the United States to make seed collections following a single technical protocol.

We developed a monitoring program to assess the health of urban fragments of pine rockland, a globally critically imperiled, fire-dependent plant community, in order to provide feedback for adaptive land management. Our results showed negative effects of fire exclusion, including low native herb and grass cover, excessive leaf litter accumulation, and high densities of native trees in most of the twelve preserves sampled.

The relationship between landscape pattern and the distribution and spread of exotic species is an important determinant of where and when management actions are best applied. We have developed an interdisciplinary approach for prioritizing treatment of harmful, nonnative, invasive plants in National Park landscapes of the Mid-Atlantic USA.

Bromus tectorum is expanding across western North America. This spread is due to its own competitive abilities, land management practices, and unintended transport by the public as the plant's spikelets often lodge in clothing. Many assume that washing in a laundry machine makes the seeds nonviable: we decided to test this assumption. We hypothesized that seeds would exhibit lower rates of germination and emergence after being laundered, and the effect would be stronger if bleach was used.

We review Miami-Dade County's Environmentally Endangered Lands (EEL) Covenant Program as a means to create protected areas on private property via financial incentives. Such incentives go a step beyond regulatory and fee simple approaches to conservation. The program is codified under Chapter 25B, Article II, of the Miami-Dade County Code as authorized by section 193.501, Florida Statutes.

The National Park Service (NPS) and other land management agencies have interest in managing bison herds under “natural” conditions; yet demographic features of natural populations are not well described. One solution to this issue involves the analysis of historical bison (Bison spp.) jump data. We conducted a literature search of archeological data associated with bison jump sites in North America with the goal of analyzing the data and summarizing historical bison demographics. We identified six locations with adequate information to conduct vertical life-table analyses.
