Texas Gulf Region Cooperative Weed Management Area

The Texas Gulf Coast Cooperative Weed Management Area (CWMA) was established in 2014 by the City of Port Aransas and initial partners the Texas A&M Forest Service and Lady Bird Johnson Wildflower Center. The mission of this CWMA is to address invasive Brazilian peppertree (Schinus terebinthifolious) from Port O'Connor to Packery Channel on the Texas Gulf Coast.

The Texas Gulf Region CWMA is a voluntary network of public and private stakeholders that are concerned with the management of Brazilian peppertree. The CWMA seeks to prevent the spread and movement of the species by advocating for cooperative control amongst willing landowners and managers.

What is the Issue?

Brazilian peppertree (Schinus terebinthifolious) is a non-native, invasive species in Texas. It is native to Brazil, Argentina and Paraguay. It was introduced in the 1800s in Florida as a landscape ornamental prior to be recognized as being a nuisance weed in the 1950s. Once sold as an ornamental in Texas, its importation, sale and distribution are now prohibited in Texas and several other states. The species was first reported in 2003 by trained citizen scientists, it has now spread along the entire Texas Coastline. To view submitted observations please click here.

Brazilian peppertree invades disturbed areas such as fallow fields, ditches, drained wetlands and roadsides. As infestations grow, they quickly form dense thickets, shading out native grasses, shrubs, and taking over native grasslands, tidal flats and other habitats. These thickets exclude most other vegetation forming mono-cultural landscapes which are unattractive to native wildlife. This species is considered one of the greatest threats to biodiversity for its dramatic effect on both plant and animal communities.

Who We Are

We are a collective group of local, county, state and federal agencies, non-profit organizations, university researchers and community representatives who have come together to fight Brazilian peppertree on Texas' Gulf Coast. The CWMA serves Aransas, Calhoun and Nueces Counties.

What is the CWMA doing?

Education and Outreach
Raising awareness of Brazilian peppertree impacts to our landscapes and sensitive coastal habitats is a main priority of the CWMA. The group regularly hosts public open houses and participates in community events to raise Brazilian peppertree awareness.

Establishing Baseline Distribution Data
To better understand the distribution of Brazilian peppertree, the CWMA is working to establish a baseline distribution and determine levels of impact within the area. Members are contributing known information, which will be stored in one central location.
To view submitted observations please click here.

Pilot Control Treatments
The CWMA is working to develop and implement pilot treatment projects to address Brazilian peppertree within the area. Treatment locations will be determined using collected observation data and treated using identified best management practices.

Upcoming Control Events:
* TBD*

February 8, 2015 - The City of Port Aransas and City of Port Aransas Volunteer Fire Department held a 56 acre prescribed burn at Charlie's Pasture Nature Preserve. The burn targeted Brazilian peppertrees and sought to promote native species.

July 16, 2014 - The City of Port Aransas and Texas Gulf Region CWMA partners held a member workday to control Brazilian peppertree near highway 361. In the collaborative control event, 2 gross acres of Brazilian peppertree were removed.

February 25, 2014 - At Charlie's Pasture Nature Preserve, over 75 community volunteers and agency cooperators worked together to control 48 gross acres of Brazilian peppertree. Texas A&M Forest Service saw crews fell peppertrees, which were removed by volunteers and loaded onto trailers to be chipped off-site.

Restoring the Landscape
In order to restore the landscape after removal of the Brazilian peppertree infestations, the CWMA is working to restore and enhance treated areas. When possible, native species will be introduced to replace the removed invasive trees.

Whenever possible, native species should be used in home landscapes. Potential non-invasive alternatives to Brazilian peppertree include:
Soapbush, Guajacum angustifolium
Prarie Acacia, Acaciella angustissima [formerly Acacia angustissima]
Guajillo, Senegalia berlandieri [formerly Acacia berlandieri]
Great leadtree, Leucaena pulverulenta
