This study can contribute to conservation planning in a multitude of aspects. Firstly, |
it is unusual to encourage stakeholders to rethink development planning, especially in |
the Florida 2070 project, from the angle of ecological value and sustainability. Driven by |
the Florida population estimation in 2070, Trend and Alternative scenarios were generated, implying two distinct land use patterns. Even though the more durable example |
is recommended, we respect the invaluable environment by effective means such as increasing development densities, as well as protecting reserve areas; all corresponding map |
projections and strategies were produced and elaborated from a biased perspective of |
development. Human–wildlife conflicts, as one of the most important subtopics of global |
biodiversity conservation [2], are widely discussed in the published literature, deeply correlating conservation interventions and conflict management [7,12,22], whereas previous |
scholars and land-use planners preferably suggested ecosystem-wise spatial planning, |
rarely addressing intractable ongoing conflicts between biodiversity conservation and social development [19,20]. This study brought in the planning topic of ‘Development versus |
Conservation’ and could be referred to as an example of incorporating and considering |
two sides of human–wildlife conflicts right from the planning stage: the demands of accelerating urban sprawl and prioritization rankings representing the need for biodiversity |
conservation. |
Secondly, we firmly convey ideas on environmental impact avoidance via spatial |
planning processes for solving conservation conflicts harnessing methodologies of inverse |
spatial conservation prioritization [35]. Aggregating and constraining human activities |
to some regions of low ecological merit is the basis of impact avoidance theory; where |
these impacts need to be prevented are synonymous with the party of environmentally |
destructive human influences in human–wildlife conflicts [16,35]. To gain more insights |
into Florida 2070 and its underlying conflicts, our close-up analysis of inverse prioritization assessment is accordingly conducted by comparing conservation ranking maps and |
development plans. The business-as-usual Trend planning follows Florida’s current urban |
development pattern, aggressively conquering undeveloped greenfield sites regardless |
of wildlife homeland. In contrast, the Alternative scenario highlights the importance of |
top-priority areas by delineating ecologically vital areas and encouraging infill and redevelopment [33,34], which reflects the idea of impact avoidance (from the conservation side) |
and a compact city approach (from the development side) by preferably utilizing land of |
least biodiversity value but suitable for exploitation, especially around the existing urban |
fringe (Figure 8a). After all, impact avoidance is convincingly a more effective measure |
than other conservation prioritization applications [13]. |
Attention should also be paid to several limitations of the present study. The first |
issue that needs to be considered and justified is the data and related data process methods |
underpinning our research. In our study, we substantially employed species data and |
accordingly relied on the quantitative computational tool (Zonation) generated maps, which |
should be questioned to some degree. Errors and uncertainty constantly occur throughout |
different stages of software-assisted conservation planning analysis due to either the quality |
of underlying data sets or mechanisms of habitat allocation models [11,49,50]. Using |
static species distribution data as surrogates of existing wildlife occurrences ignores some |
inherent traits of species activities, such as unpredictable population dynamics and complex |
Land 2022, 11, 2182 14 of 23 |
species interactions [21,49,51]. Available species distribution data used here merely act |
as the role of indicator or subset of the whole population occurring in South Florida [52]. |
In addition, generally collected via VHF or GPS collars [36,53,54], a species location data |
downside of hysteresis is intractable and unsolvable, which leads to common dilemmas in |
planning processes, in that regional biodiversity status or ecological planning issues have |
not been analyzed and presented to governors or other stakeholders until vital planning |
strategies and development decisions are grounded [55]. With the purpose of reminding |
urban planners or decision-makers of Florida’s regional ecological value, the result of data |
analysis, such as the conservation prioritization ranking map in our case, is not sufficiently |
the best surrogate of Florida’s representation of biodiversity resources, acknowledging that |
there are other alternative conservation planning methods with other concentrations which |
are also worth being explored (the choice between protecting already endangered species |
or potentially endangered species) [20]. |
Concerning human-based population data, Florida 2070 Project’s projections laid the |
foundation for our further overlay analysis, which was incorporated with Zonation SouthFlorida-species-based results to undertake top-priority and lowest-priority reassessment |
and inform us of the battle between wildlife conservation and human development shown |
by the above maps. Even so, 2070 projections are not undoubtedly perfect and to some |
extent, the predictions would never become a reality. Essentially, urban planning scholars |
tested and used different assumptions for Trend 2070 and Alternative 2070 regarding |
different population and development aspects [34]. However, Trend 2070 and Alternative |
2070 share the same criteria and weights for examining each cell for determining its |
suitability for future urban development outwards or infill, which implies the two plans’ |
identical one-sided intentions for human development, rather than regarding conservation |
value. For sure, the compact scenario would do less harm to the environment by selectively |
preserving necessary habitats, most of which are constituted by large or connected managed |
areas, while preferably overlooking the irreplaceable biodiversity importance of small, |
isolated habitat patches [56]. Besides, the outdated 2010 Baseline is one of the primary |
data sources for 2070 projections, on which established information mainly includes 2010 |
gross development density, 2010 land cover pattern and 2010 population distribution. |
As Figure 9 and Table 3 show, by comparing 2014–2019 land use and cover map (data |
from Florida Geographic Data Library, University of Florida GeoPlan Center) with 2010 |
Baseline, the increase in developed area (+61.5%) is beyond astounding in less than twenty |
years, much higher than the 2070 Trend has expected (+38.3%). Trend 2070 failed to |
foresee the dramatic infill development that already occurred within urban regions in |
recent years, which is the plausible main driver of excessive growth in developed lands. |
Even though Trend 2070 has plotted the extensive conversion of unused land resources to |
future developed lands, without thoughts of urban redevelopment, the sum of Trend 2070 |
developed lands (11,735.0 km2 |
) is still less than that of Current 2014–2019 (13,698.0 km2 |
) (in |
order to present the full map of the study site, the nuances of infill developed land increase |
might seem implicit in Figure 9). In addition to unplanned area increase, current land use |
conditions spatially matched the ‘leap-frog’ urban sprawl pattern [57–59]: human beings |
have aggressively exceeded the domain of developed lands in Baseline 2010 and even went |
beyond the estimated future developed area projected in 2070 Trend projection, as well as |
recklessly infecting harm on several of the most critical reserved areas in South Florida, |
including the Florida Keys. Unexpected current development conditions and random |
habitat loss seen below not just uncover underestimations and drawbacks of the Florida |
2070 project but also disclose an accelerating pace of landscape conversion, in the sense |
that actual development pattern and progress should always be deemed sophisticated, |
dynamic, changeable and unpredictable to some extent. The social preferences reflected by |
the Florida 2070 project are inevitably restricted by its out-of-date information sources and |
slightly arbitrary propositions for different land-use patterns. |
