STORM WATER RETENTION PONDS; AN IMPORTANT SOURCE OF AQUATIC MACROINVERTEBRATE DIVERSITY IN A SEMI-ARID URBAN LANDSCAPE
Denton, Texas which is located in a semi-arid region has over 200 constructed ponds. Many of these ponds, function to control stormwater runoff. The value of these waters to regional biodiversity and as greenspaces is important but generally undervalued. This study monitors habitat variables and macroinvertebrate diversity in ponds selected to represent a gradient of urban influences to their water quality and habitats. The objective of the project is to identify factors controlling aquatic invertebrate diversity. Taxa richness was similar between the ponds but composition differed. Submerged vegetation had the most underwater complex leaf structure and the highest abundance, exceeding 1000 individuals per m3 and the greatest diversity of Diptera and Trichoptera. Emergent vegetation averaged approximately 800 individuals and Typha averaged 500 individuals per m3. Ponds with more open water had a significant decrease in odonatan diversity. Study results will be used to develop a conservation plan to increase the ecological health of the ponds. If managed correctly, these systems can be incorporated into a sustainable development that provides cleaner water and beautiful green spaces for the citizens of the City of Denton.
