Over 1,500 mammals, birds, reptiles, invertebrates, fish and amphibians live in this lushly planted sub-tropical zoo and botanical garden. Emphasis is placed on creating a "survival center" for rare and endangered species. The multi-million dollar facility was built, stocked, staffed and then given to the citizens of South Texas in 1971 by the Earl C. Sams Foundation. Numerous awards have been bestowed on the Gladys Porter Zoo for the breeding of rare and difficult species. An average of 360,000 guests visit the Zoo annually. The Zoo's mission statement reads: Gladys Porter Zoo.....a visitor oriented zoological and botanical park dedicated to the preservation of nature through education, conservation and research.....


The Gladys Porter Zoo opened to the public on September 3, 1971. The facility was completely planned, built, stocked, equipped and then given to the City of Brownsville by the Earl C. Sams Foundation.

During the 1960s, Gladys Porter became increasingly interested in the plight of the world's wildlife when she and her husband, Dean, traveled extensively in Africa and other foreign countries. The idea of a zoo for the Rio Grande Valley developed at this time, and the members of the Sams Foundation decided that this would be their next major project. Mrs. Porter was closely involved with the planning, construction and stocking of the Zoo.

Over the years, the Earl C. Sams and the Lightner Sams Foundation have provided a major portion of the funds required to operate the Zoo. However, in 1986, due to changing financial conditions, the Board of the Valley Zoological Society voted to establish a permanent endowment fund to help strengthen the financial status of the Zoo. The Sams Foundation made their commitments through the establishment of challenge grants totaling $3 million. The Earl C. Sams Foundation committed to match dollar-for-dollar up to $2 million. The Lightner Sam's Foundation committed to match an additional $1 million on the same dollar-for-dollar basis to the Endowment. Since the endowment fund's formation, over $10 million has successfully been raised from businesses, corporations, foundations and concerned individuals. Income from the permanent endowment fund has ensured that sufficient funds are available each year to maintain and improve the quality of the Zoo's operations.

A few things have changed over the years, but many things still remain the same. The Gladys Porter Zoo is still dedicated to the preservation of nature through education, conservation and research. These traditions are alive and apparent in the day-to-day operations of the Zoo and it is with these basic missions in mind that the Gladys Porter Zoo continues plans for the future.

Rental fees for these areas are a minimum of $325 which includes the first two hours of use and $162.50 per each additional hour. This includes table and chair set up with proper prior notice and coordination, but additional fees will be charged if extensive decoration or set up are requested.
