WHY TWCA?
The Turfgrass Water Conservation Alliance (TWCA) is committed to improving plant material that leads to water conservation. The organization’s science-based approach relies on 3rd party peer review data to qualify only the turfgrasses that demonstrate a statistically significant water saving potential.
MOST RIGOROUS DROUGHT TESTING | UNBIASED QUALIFICATION | USES UP TO 40% LESS WATER
DROUGHT TOLERANT TURFGRASS
40% Less Water
TWCA qualified cultivars can use up to 40% less water while still maintaining a green and healthy surface for people to enjoy. Maintaining green turfgrass while using less water benefits the environments ecosystems, cools the temperature and boosts mental and emotional health.
Third Party Validated
TWCA's approach to conservation relies on 3rd party peer review data to qualify turfgrasses that demonstrate statistically significant water savings over conventional varieties. Researchers across North America collaborate with TWCA eliminates confounding factors such as soil type, heat, and pest management from the results.
Digital Image Analysis
DIA photography is used to analyze the percent green color in each plot by capturing RGB percentages. As plots go through drought stress, the photos reveal the most resilient varieties. The trial runs until all plots are below 25% green cover, the data is then analyzed and given to the TWCA research committee to determine which varieties qualify.
Every Drop Counts
Drought Tolerance is one of the most important traits that we work on in all our species. In a world where water shortages are becoming more and more common, developing varieties that use less water and educating the public, local municipalities and governments about these varieties that can be a water savings and still add a lot of benefits to the environment is extremely important.
