1. Introduction |
Human population increases and corresponding unprecedented global biodiversity |
declines have escalated a looming social and environmental dual-crisis that may trigger |
dreadful consequences for human society as well as global and regional ecosystems [1–4]. |
In the past few decades, the framework or paradigm of human–wildlife conflict has been |
extensively applied by scholars and relevant literature has increased considerably [5], |
nonetheless inherently addressing the opposing positions of we human beings and nature [6]. The seeming dichotomy between development and conservation ignores genuine, |
intertwined sophisticated relationships and interactions between humans and nature [6]. |
Thus it is a more rational and arguable viewpoint to recognize two parties of conflict as |
a whole. Humans can take conservation actions to reconcile conservation conflicts rather |
than resolving or eliminating them [7]. To balance society development and biodiversity |
conservation and accomplish a ‘win-win’ situation for humans and nature [7,8], it is necessary to identify underlying objectives held in both ecological and social dimensions, |
especially for the commonly imperceptible human–human conflicts that interactively shape |
social values [9]. |
Conflict reconciliation involves processes in multiple aspects, including conflict mapping, conflict planning, demonstrations of strategies and evaluation of outcomes [10], |
among which spatial conservation prioritization (SCP) is an effective land-use planning |
tool that can be capable of the evaluating biodiversity status of specific regions in a balanced approach and utilized for mitigating conflicts in advance [2,11,12], through specific |

measures such as ranking for high-priority areas, identifying green corridors, ecological |
network delineation, allocation of habitat restoration and offsetting distribution [13–16]. |
Underpinned by previous landscape planning studies which employed traditional conservation prioritization methods [2,17–19], their contributions are indisputable in informing |
ecological protection efforts with transparent trade-offs [17,20], but these studies neglected |
the flip side of urban planning zoning issues, which are precisely the non-biodiversity or |
human-dimensional aspects [8,14,17,21]. These social dimensions should be considered, |
along with interests in biodiversity conservation in the policy-making stage. Once the |
natural and social science factors are connected [22,23], assessment of human–animal conflicts [24] can assist urban planners to explore trade-offs effectively and explicitly from a |
more comprehensive perspective [8,25]. |
With highly urbanized areas and ecologically-valuable reserves, the sunshine state |
urgently requires effective conservation planning solutions to manage and diminish continued human–wildlife conflicts under the background of continuous biodiversity loss, future |
sea level rise scenarios and competing land use [19,26,27]. Florida’s severe human–animal |
conflicts are provoked by the tension between its exceptional position as a harbor for many |
global biodiversity hotspots [28,29] and decades of high-speed population increase [30]. |
Within such a particular context, the Florida 2070 joint project was collectively implemented |
by local governors and academic research groups intending to explore distinct developmental pathways to accommodate projected human population growth by 2070 [31,32]. In the |
Florida 2070 projections, two different scenarios (Trend and Alternative) were generated |
based on varying human development assumptions, where one follows the present inefficient urban sprawl pattern and the other stands for the compact development approach. |
Although these two variable projections are hypothetical and with stochasticity, they can |
certainly be comprehended as a synthesis of general human development preferences [8], |
or, in other words, crucial social science evidence for potential land-use planning analysis. |
The Alternative 2070 scenario suggests a land-use planning method using the ’compact city approach’ [33] by assuming a new population for redevelopment or infill development [34]. Compact land-use pattern aims to spare considerable greenfield sites |
for conservation purposes, which has similar outcomes to another conservation planning |
application, impact avoidance [16,33]. As an efficient environmental zoning approach, |
impact avoidance can be easily achieved by techniques of inverse spatial conservation |
prioritization [13,35]. In this study, we took advantage of this robust approach to make our |
SCP identification and succeeding analysis more complete. |
This paper uniquely combined scientific evidence from the human and nature conservation sides by reassessing Florida’s future development projections with a two-sided |
spatial conservation prioritization analysis method to help acknowledge a holistic view |
of conservation conflicts in Florida. Linking impact avoidance with conflict reconciliation |
within the study area of South Florida, our approach identified and analyzed highest and |
lowest priority areas and integrated with different land use patterns to reveal intractable |
development–conservation conflicts early in the planning phase and seek a durable winwin scenario for all parties of the ecosystem. As long as relevant multi-dimensional data are |
available, we encourage future conservationists and decision-makers elsewhere to adapt |
our reassessment methods and contribute to sustainable regional planning strategies to |
minimize further biodiversity loss. |
2. Materials and Methods |
2.1. Study Area |
Florida hosts the most significant biodiversity among all U.S. states and has more |
than 16,000 kinds of native species found nowhere else on the planet [27]. However, the |
sunshine state suffers the most from booming population growth and aggressive urban |
sprawl. Unlike most existing literature on Florida conservation, our studies focused on |
South Florida to address land-use issues and human–wildlife conflict, which are common |

global problems. South Florida distinguishes itself from other ecoregions in Florida by its |
uniqueness in natural and human-dimensional factors. |
The southern region of Florida, our study site (Figure 1), covers 55,604.4 km2 and |
ranges from the upper Lake Okeechobee to the end of the Florida Peninsula along with |
Florida Keys islands, consisting of 16 counties: Broward, Charlotte, Collier, Desoto, Glades, |
Highlands, Hendry, Indian River, Lee, Martin, Miami-Dade, Monroe, Okeechobee, Palm |
Beach, Sarasota and St. Lucie. South Florida mainly encompasses subtropical and tropical |
climate zones, with annual average precipitation of 59 inches and temperatures ranging |
from 47◦ |
to 90◦ F [36]. The study area of our assessment involves 4 substantial National |
Parks administered by the National Park Service (NPS) and 70 wildlife management areas |
(WMA) preserved by the Florida Fish and Wildlife Conservation Commission (FFWCC), |
respectively taking up 91.43% of National Park area and 36.3% WMA (Florida Geographic |
Data Library). Many unique ecosystems and corresponding wildlife habitats are located |
within these protected areas in South Florida, such as Lake Okeechobee, the Everglades |
Wetland, the Big Cypress Swamp and the Florida Keys islands [37]. With such a robust |
ability to support an amazingly diverse group of flora and fauna, our study area should |
undeniably receive recognition as one of the most vital biodiversity hot spots statewide and |
be among the highest global rankings for ecological conservation [27,38,39]. The species |
richness of our study areas has not been quantified and collected by reliable literature. |
However, there are more than 68 threatened animal species (USFWS 1999) merely within |
the Greater Everglades ecosystem that comprehend a total of 1033 plant taxa, 59 reptile |
taxa, 76 mammal taxa, 432 fish taxa, 349 bird taxa, 38 amphibian taxa and 459 bird taxa [37]. |

and conservation trajectory, as well as explicating and disclosing severe human–wildlife |
conflicts within Florida and even worldwide. |

2.2. Framework of Reassessment Procedures |
With the goal of resolving conservation conflict in Florida, available data sets of the |
study area and advanced quantitative planning tools were preferred as our pieces of evidence and methods underpinning advanced studies. In order to clarify and confirm the |
following research procedures, we articulate a reassessment framework for our study in |
Figure 2, including five successive stages: (1) collection of land cover data and Florida |
2070 Project data as social science evidence; (2) acquisition of biodiversity distribution |
data from listed focal species in our study site as nature-side data; (3) using a quantitative |
