Program Update
Sustainable LandscapesNatural Resource Summit
October 29-30, 2008
Dr. Amy ShoberUF/IFAS Gulf Coast REC
Mission of the CLCE
To protect and preserve Florida’s natural resources and quality of life through interdisciplinary research, education, and outreach. Areas of concern include water quality and quantity, wildlife habitat, landscape design practices, and sustainable resource use.

Sustainable Landscape Construction & Materials
Fine Gardening Nov/Dec pg 41
Small Garden 2006 pg 211
• Joint project with Pinellas County Extension Office- Sustainable Living Program
• Focus is on hardscape materials and techniques such as: • pervious pavers• manufactured lumber • recycled materials • non-toxic paints and
stains• stormwater harvesting
techniques
Landscape Perceptions & Behaviors
• In cooperation with University of Central Florida, Stormwater Management Academy, Leesa Souto, PI
• Purpose: ─ Understand socially
acceptable landscape design elements and plants for stormwater management and water protection.
─ Determine what influences people to change their landscape

Using Weather and Climate Forecasts in Water Resource
Management• Diverse Sources:
– 13 Regional Wellfields– Surface waters– 15 billion gallons of off-
line reservoir storage– Desalination plant (25
MGD)• Use of forecasts to
make better allocation decisions and minimize environmental impact
A Design Tool to Evaluate and Size Rain Barrels for the Florida
Landscape• How big should it be for my
landscape?• How often might supplemental
water be needed? How much?

Nitrogen Fertilization of Landscape Plants
Objectives:1. To determine fertilizer requirements of
a range of common landscape plants (i,.e., warm & cool season annuals, perennials, vines, groundcovers, and shrubs)
2. Verify current UF/IFAS fertilization recommendations
Experimental Design:· 5 rates of N fertilizer
0, 2, 4, 6, & 12 Lbs / 1000 ft2
· Slow-release N applied every 6 weeks
Nitrogen Fertilization of Landscape Plants
Results:Finishing warm season annual evaluation
currently.For some spp., recommendations may be too low.
Impacts:More accurate fertilizer recommendationsGrouping of plants with similar fertilizer need
Salvia – 2 lbs N
Salvia – 12 lbs N
Vinca – 12 lbs N
Lantana – 0 lbs N
