“…Indeed, as pointed out before by Debrot et al (2011) in most parks around the world, monitoring activity only uses up a small part of the total park budget, at most only a few percent of total annual budget expenditures are dedicated to monitoring (and research) (Casanovas et al 2014, IFG 2014a, IFG, 2014b, NPS 2008). …”

A. O. Debrot, J.E.Tamis, D. de Haan, M. Scheidat, J.T. van der Wal, 2017 was formally established on September 2, 2015. It is currently composed of two sectors: one surrounding Saba and the Saba Bank and one covering the EEZ waters of Bonaire. In order to help establish an effective cetacean conservation management plan for the Saba and Saba Bank sector of the sanctuary we here review the main marine mammal threats, help identify main management goals and make both governance and management recommendations based both on stakeholder interviews and a management review of functioning marine mammal sanctuaries in the WesternAtlantic.There are 8 species of marine mammals known to occur in the windward Dutch Caribbean YarariSanctuary. The sanctuary has relatively low levels of human activity. Based on our review, cumulative contaminant impacts -such as oil contamination originating from St. Eustatius -are potentially highest, followed by collision impacts due to the relatively high level of shipping traffic. Other factors such as, fishery entanglement, bycatch-impacts and marine debris impacts are likely low compared to many areas directly outside the sanctuary. While whale & dolphin watching impacts are still probably negligible, the impacts of anthropogenic noise, climate-change impacts and cumulative impacts still remain unknown but are potentially high.Five main clusters of interrelated goals and objectives were identified based on expert and management stakeholder interviews. The most essential proximate goal for management should be to establish a minimum structural level of institutional capacity. Under the reigning conditions of resource limitation, the next key goal should be to establish effective collaboration towards jointly achieving the higher management goals and objectives.Based on our review of species, threats, operations of other sanctuaries and expert and stakeholder input we list 23 priority recommendations and action points towards implementation of cetacean conservation for the Saba and Saba Bank Yarari sector. Governance• Use the Saba Bank Management Unit (SMBU) governance model for Yarari management implementation.• Consider merging Yarari tasks into the SMBU to effectuate resource pooling and prevent management fragmentation. Legal resources• Design and implement a simple legal mandate for Yarari management.• Copy and implement international legal guidelines for whale watching.• Revise the Fishery Framework Act BES (Vissery Visserijwet besluit BES) or draft a Decree (Regeling) under the Nature Conservation Framework Act BES (Wet Grondslagen Natuurbeheer en-bescherming, WGN) to forbid all forms of pelagic (not benthic) longline and purse seine fishing in Yarari waters.• Devise and implement legal measures and guidelines to safeguard Yarari from anthropogenic noise pollution. Finances• Based on the review of functioning sanctuaries, and current stressor levels, a basic annual budget of US$ 150 K will be sufficient to implement satisfactory marine mammal conservation.• Focus expenditures on mana...

“…The use of these macrolichen indicators has shown to have robust relationships with modeled nitrogenous pollutants at the national scale (Seed et al 2013). In the USA, Casanovas et al (2014) proposed a citizen scientist-based survey methodology for macrolichen diversity in which parataxonomic units (PUs), as identified in lichen photographs, served as species surrogates to estimate lichen diversity. Although in most cases the authors showed that the observed and estimated cumulative richnesses from both techniques were not statistically significantly different from each other, the extensive use of these approaches in biomonitoring surveys should be carefully evaluated, as misidentifications of morphologically similar species could led to wrong interpretation of data, e.g., in terms of relative abundance of functional groups.…”

“…In contrast to citizen scientists, paraecologists and parataxonomists are employed and are full members of a research team. Paraecologists or parataxonomists on the one hand, and citizen scientists on the other, have often been mentioned in the same breath in connection with biodiversity data sampling (e.g., Abadie et al 2008;Cardoso et al 2011;Casanovas et al 2014). We reviewed 4 currently running paraecologist or parataxonomist approaches and compared these with the citizen science approach.…”
