The La Costa Glen Preserve (or Habitat Conservation Area) was deeded to the Center for Natural Lands Management (CNLM) in January of 2013 as mitigation for the La Costa Senior Retirement Facility development. It is located in the southern portions of the City of Carlsbad and supports very high quality habitat. The vegetation is very dense and the terrain is steep and rugged.

Conservation Significance

The Preserve supports coastal sage scrub, southern maritime chaparral, and southern willow scrub vegetation communities. In 2013, five pairs of coastal California gnatcatcher (Polioptila californica californica) were observed. The site also supports the listed Del Mar manzanita (Arctostaphylos glandulosacrassifolia) and several other sensitive species.  The Preserve is part of the City of Carlsbad’s Habitat Management Program and represents one of the last and largest remaining stands of southern maritime chaparral.

Our Work

CNLM staff are working diligently to remove non-native plant species, such as Veldt grass (Erharta calycina), which is scattered in open areas within the Preserve.

The Preserve historically was overrun with homeless encampments and weekly patrols are currently required to prevent the homeless from using the Preserve that often leads to destruction of habitat, and increasing risks for imperiled species.

Our goals also include  sensitive plant and animal surveys, vegetation monitoring, and wildlife movement studies.

Public Access

Due to the vulnerability of the species and habitats that exist on this Preserve, it is not open to the public.
