“…This rich ecosystem, defined as the rainforest of the sea, has ecological, economical, medical, recreational, and cultural values for communities. Human activity is one of the main factors that threaten the health of corals (Chunga, et al, 2019). Increase in sea temperature, sea level, and sea pH are broader threats that are associated with climate change.…”

“…Observations and experimental results to date in the KHFMA (Kelly et al, ; Williams et al, ) suggest that in the future it should be possible to quantify the biomass densities of the habitat‐engineering large adults of excavating species of parrotfishes that would be required to prevent coral overgrowth by algae. Conservation of reef corals in Hawaii also would benefit by implementing more stringent size regulations for parrotfishes (Chung, Oliver, et al, ). The KHFMA example represents a case in which local impact is being fuelled by local anthropogenic nutrient input (Kelly et al, ), but larger‐scale spatial protection of herbivores is now generally recognized capable of more expansive improvements in algal–coral relations (Chung, Wedding, et al, ).…”

Surprisingly little published information exists on the pros and cons of managing extracted resources that are pooled as compound taxa such as species complexes. Current fisheries management includes many species complexes; in Hawaii, this includes two taxa of species pooled at subfamily and higher levels. These include seven species of parrotfishes (Scarinae, Labridae) and a seven‐species ‘bottomfish’ complex (the ‘Deep‐7’: comprising six species of snappers [Etelinae, Lutjanidae] and a single species of grouper [Epinephelidae]). Recent research on key vital rates (growth, reproduction) for major species in both taxa indicates that these complexes consist of species with disparate life histories. Species in the parrotfish taxon exhibit fast to very fast growth and short to moderate longevities, whilst Deep‐7 bottomfishes exhibit moderate to very slow growth and long to very long lifespans. These data clearly indicate that, although pooling species is a tempting default option in data‐poor situations, it is at best a necessary evil to be avoided when sufficient data on the demographics of component species become available. Pooling species is especially problematic when the ecosystem effects of extracting functionally dominant species should be an important management consideration in addition to that of species demographics. Assessments that recognize and quantify the ecosystem importance of habitat engineers and other ecological dominants could substantively improve management of species complexes. Ultimately, complexes of resource species need to be evaluated and managed based on many, sometimes conflicting and sometimes reinforcing, but always careful considerations such as those contrasted herein between the parrotfishes and bottomfishes of Hawaii.

“…Herbivore management areas (HMAs) are spatially managed areas where the take of herbivorous fishes and invertebrates (e.g., sea urchins) is prohibited while other extractive and nonextractive uses are allowed. Increasing herbivorous fish biomass, particularly through the use of spatial networks have been dominant recommendations of resilience-based management (McLeod et al, 2009;Graham et al, 2013;Green et al, 2014;Chung et al, 2019). Herbivores are good candidates for spatial strategies because of their high site fidelity (Howard et al, 2013) and in previous usage spatial management and herbivory showed a strong connection to shaping benthic communities (Graham et al, 2011).…”

“…In 2016, DAR initiated the development of The Hawai'i Coral Bleaching Recovery Plan, which evaluated alternative management options following the major bleaching events through a combination of a systematic literature review and global and local expert opinion. Establishing a network of HMAs was identified as the top-ranked intervention based on its potential to promote coral recovery and management effectiveness (Chung et al, 2019).…”

Building Coral Reef Resilience Through Spatial Herbivore Management

Coral reef managers currently face the challenge of mitigating global stressors by enhancing local ecological resilience in a changing climate. Effective herbivore management is one tool that managers can use in order to maintain resilience in the midst of severe and frequent bleaching events. One recommended approach is to establish networks of herbivore management areas (HMAs), which prohibit the take of herbivorous reef fishes. However, there is a need to develop design principles to guide planning and implementation of these HMAs as a resilience-building tool. We refine available guidance from fully protected marine protected area (MPA) networks and developed a set of 11 biophysical design principles specifically for HMAs. We then provide a case study of how to apply these principles using the main Hawaiian Islands. We address site-specific considerations in terms of protecting habitats, including ecologically critical areas, incorporating connectivity, and addressing climate and local threats. This synthesis integrates core marine spatial planning concepts with resiliencebased management and provides actionable guidance on the design of HMAs. When combined with social considerations, these principles will support spatial planning in Hawai'i and could guide the future design of HMA networks globally.
