Table 4. Study objective was to model susceptibility scenarios resulting from urbanization and sea level rise (SLR) to understand |
their potential future impacts on the Peninsular Florida Landscape Conservation Cooperative conservation targets, completed in |
2018. The area (km2 |
) and percent (%) decrease in area of each model input (i.e., conservation target) for the Freshwater Aquatics |
Priority Resource for each future model scenario of urbanization (Urban) and SLR. The Baseline area of target represents the current |
extent of the input model data with the 2010 urban baseline extracted. Each area and percent decrease in area is represented for |
Critical Lands and Waters Identification Project Priority 1 and 2 (CLIP P1 and CLIP P2, respectively). The CLIP Landscape Integrity |
Index values 8 (high ecological integrity) were used for calculations. We also present the area and percent change in area for the |
entire Freshwater Aquatics Priority Resource for CLIP P1 and CLIP P2. |

Gopherus polyphemus, red-cockaded woodpecker Picoides borealis, Sandhill bird index), especially for the |
gopher tortoise and the sandhill bird index (brownheaded nuthatch Sitta pusilla, northern bobwhite Colinus |
virginianus, Bachman’s sparrow Peucaea aestivalis). Projections indicate that urbanization will cause greater |
losses than SLR for High Pine and Scrub. For the Coastal |
Uplands Priority Resource, the high SLR scenarios |
showed the greatest percent loss in area for the |
conservation targets (Table 3), especially in 2070. Many |
of the projected Coastal Uplands losses in area from SLR |
were high, with the greatest at 46.8% projected loss for |
Ecological Greenways. We determined the mean elevation of Coastal Uplands to be 1.46 m (SD ¼ 1.44 m) by |
using the U.S Geological Survey (2019) digital elevation |
model, with the most frequent elevation observed |
(60.02%) at 0–1 m. The general pattern of a greater loss |
in area due to urbanization and SLR in 2070 than in 2040 |
was less pronounced for the Freshwater Aquatics Priority |
Resource, but still resulted in loss (Table 4). We found a |
lower percentage of Freshwater Aquatics area lost from |
future SLR than High Pine and Scrub and Coastal |
Uplands Priority Resources, with the highest Freshwater |
Aquatics area lost at 5.3%. |
We combined CLIP Priority 1 and 2 percent decrease in |
area (Tables 2–4) to compare projected losses from high |
vs. intermediate SLR, holding urbanization constant, for |
each Priority Resource. Coastal Uplands showed the |
greatest difference in percent area lost between high |
and intermediate SLR (Figure 2). The mean difference for |
all urbanization scenarios in percent area lost between |
high and intermediate SLR was greatest for Coastal |
