UF/IFAS Survey Shows Homeowners Want Incentives to Conserve More Water

Homeowners with irrigation systems would use less water if they were offered more incentives, according to a new UF/IFAS report. Most will even pay more for better water quality.

Respondents to a UF/IFAS online survey of 3,000 such homeowners in Florida, Texas and California said reducing the price of water efficient equipment would be the most effective strategy. That was followed by more practical information on household water conservation, easier identification of water efficient appliances and better landscape irrigation ordinances.

Additionally, respondents liked the idea of a real-time water use mobile app and more information on the environmental impacts of water conservation.
"Efforts in promoting the adoption of water-saving irrigation systems and practices will be more successful when environmental conservation measures are combined with economic incentives such as utility or manufacturer rebates on smart irrigation equipment." said Hayk Khachatryan, an assistant professor of food and resource economics and the lead investigator in the survey.

To get better quality water, 64 percent of survey participants said they're willing to pay higher monthly water bills. Of those, 26 percent said they'd pay less than 5 percent of their current bill, 30 percent would pay 5 percent to 15 percent more and 8 percent were willing to pay more than 15 percent.

UF/IFAS researchers asked participants about governmental and non-governmental incentives that may contribute to consumers' purchase and installation of water conserving items. Of those surveyed, more than 80 percent said they do not receive government or utility company financial support for water conserving purchases.

Government or utility company incentives to purchase these items were fairly scarce. About 18 percent of respondents said they received an incentive to install low volume/dual flush toilets. Only 17 percent said they received rainwater collection tanks, and only 16 percent received flow restrictor taps/low water shower heads.

 DBH or Caliper: Know the Difference
From: RPG Times, Fall 2016

Diameter at breast height or DBH is trunk diameter measured 4-5 feet from the ground. DBH is the standard method for recording trunk diameter for trees growing in the woods in the traditional forestry industry. 

However, it has no place in the horticultural or nursery professions. The standard for measuring trunk diameter in urban forestry and in the nursery and landscape industry is trunk caliper, not DBH. Trunk caliper is the measurement of trunk diameter 6 inches from the ground. If trunk diameter measured 6 inches from the ground is greater than 54 inches, then measure diameter 12 inches from the ground. It is as simple as that. If you are in the landscape or nursery industry, or are planting trees in the urban forest, or you are specifying or inspecting trees planted in your city, do not use DBH. DBH has no meaning and is inappropriate for urban and suburban landscape plantings. The Florida grades and standards for nursery stock published by the Florida Department of Agriculture and accepted as the standard for nursery stock uses caliper to specify trunk diameter. Please leave DBH where it belongs, as a useful tool for measuring trees for timber sales in the forest. 
Palm Trunk Sampling for Phytoplasma (Texas Phoenix Palm Decline)  

Dr. Brian Bahder is the new vector entomologist at the Fort Lauderdale Research and Education Center. He is specializing in vectors of the palm phytoplasmas that cause Texas Phoenix Palm Decline (TPPD) and Lethal Yellowing (LY). He began in July of 2016 and has a 30% extension appointment.
He has already developed a new technique for palm phytoplasma detection using the internal wood shavings from symptomatic palms. It is faster and more sensitive and can determine which palm phytoplasma is present. It uses a new technique called digital PCR.
Sampling technique instructions for TPPD can be found here. The cost is still $75. The preference would be to send palm trunk samples to Dr. Bahder at the FLREC.

Samples can still be sent to the Gainesville lab, if you prefer, but they won't be able to tell which phytoplasma is present.
