Banc-des-Américains MPA : monitoring indicators, measures and state of knowledge
Notice bibliographique
Résumé
Priority issues were identified to link the conservation objectives (COs) with the choice of pressures. Priority issues also help to clarify the direction of the changes expected to assess the status of the indicators and measures. Conservation priorities, pressures and indicators The 15 conservation priorities, 12 pressures, and 44 indicators were reorganized from the 2018 list and, in some cases, slightly modified to better reflect the databases used. Five indicators were removed from the 2018 list, and three pressures and five indicators were added regarding competitors/predators (grey seal), scientific activities, fishing violations, new pressures and ghost gear. As a result of the review, acidification and dissolved oxygen become two separate indicators from Pr2 to allow for a more appropriate interpretation. Method for assessing the status of measures and indicators Two methods are proposed for assessing the status of the measures and indicators presented: anomaly and fixed threshold. Other approaches may be considered for indicators not presented. Anomaly method: Anomalies (deviation from the standardized mean) are used to highlight the variation of a measure against a reference period. Fixed-threshold method: Thresholds are used instead of anomalies when threshold values with known biological effects from the scientific literature are available. Known thresholds have been used for measures relating to herring, dissolved oxygen and acidification. The data used must be properly processed according to their nature and statistical properties (e.g., data transformations) before the anomaly is calculated. The status assessment can be (1) directional when the change has an a priori favourable or unfavourable direction or (2) bidirectional when there is no anticipated direction to the change. In this case, it is the magnitude of the change that is assessed. Three status categories are used, and each category is assigned a score from 1 to 3. Data may be presented without an its status evaluated due to a lack of information, in which case the “Not assessed” category is used. The status of the indicator is the sum of the anomalies of each of its measures or, when thresholds are used, the sum of the scores associated with each measure. An oceanographic area and a benthic area wider than the MPA boundary were defined in order to calculate measures for eight indicators. Measures and state of knowledge For each of the 27 indicators with a processed database, measures were selected, described and calculated according to a reference period in order to produce the state of knowledge for the available time series. The relevance of the grouping of measures considered for an indicator was reviewed and commented upon. A confidence level was established for each of the 27 indicators, based on the quality and quantity of the data used. The following indicators could not be assessed: BD2–Warm water indicator species, EP2–Atlantic wolffish bycatch, EP6–Cetacean mortality/accidents, Pr8–Intensity of observation and recreational activities, Pr10–Number of entanglements, and Pr18–Number of new pressures. A basic portrait is nevertheless presented for these indicators. The final status (overall rating) of the indicators will be produced in the monitoring reports after a few years have passed since the establishment of the MPA status. In this report, only changes in the status of the indicators over the time series are presented. Priority indicators Priority indicators have been identified for the production of interim reports, which are more succinct than full monitoring reports, every 3 years. These indicators focus on direct pressures and a few key indicators related to CO1 (conserve and protect benthic habitats) and CO3 (promote the recovery of at-risk whales and wolffish).

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
