Náttúrulegt birkilendi á Íslandi er kortlagning yfir alla náttúrulega birkiskóga og birkikjarr á Íslandi. Helstu upplýsingar eru hæð, þekja og aldur. Skilið er á milli núverandi hæðar og aldur fullvaxta birkis. Það er gert samkvæmt alþjóðlegum skilgreiningum um hæð trjágróðurs þar sem miðað er við hæð fullvaxta skógar. Birki var fyrst kortlagt á árunum 1972-1975 og var unnin leiðrétting á gögnunum og gerðar frekari greiningar á árunum 1987-1991. Gögnin voru því komin nokkuð til ára sinna þegar ákveðið var að hefja endurkortlagningu á öllu náttúrulegu birki á Íslandi. Fór sú vinna fram á árunum 2010-2014 og er núverandi þekja því afrakstur þeirrar vinnu. Flatarmál náttúrulegs birkis á Íslandi er 150.600 ha. Frá árinu 1987 hefur flatarmál birkis með sjálfsáningu aukist um 9% og nemur 13.000 ha. Gögnin voru upphaflega hugsuð fyrir mælikvarða 1:15.000, hins vegar var talsvert stór hluti landsins kortlagður í mælikvarða 1:5000 – 1:10.000.

The objective of the study was to describe the spatial distribution of krill in eastern Canadian waters using a statistical modelling approach in support of the identification of important habitat for the western North Atlantic (WNA) blue whale (Balaenoptera musculus). Generalized Additive Models (GAMs) were used to predict ‘Significant Aggregations of Krill’ (SAK), i.e., areas where dense krill aggregations would have a greater probability of occurring. SAK cover less than 2% of the entire spatial domain and their location varied among krill categories and seasons. These SAK are interpreted as areas where environmental conditions promote krill aggregation on a regular basis and therefore are potentially important for WNA blue whale foraging in eastern Canadian waters.

Deep arctic sponge aggregations. This habitat can be described as a type of deep-sea sponge aggregation (sensu OSPAR 2010) occurring only in the deeper, colder water (Arctic modified, and Norwegian Sea Deep Water), where glass sponges (class Hexactinellida) are typical and other strictly deep-sea sponges are common. One of the most common species of glass sponge is the Caulophacus arcticus, which is generally found on hard sea bottoms on the lower part of the continental slope.

Walk-in lakes and the buffers around the walk-in lakes within the old Clearwater Forest District circa 2001. The old Clearwater Forest District became the northern part of the Thompson-Rivers Natural Resource District. Walk-in lakes were identified for non-motorized access only.

PURPOSE: The objective of the sea scallop survey is to obtain fishery independent data on the abundance, size distribution and location of scallops in the southern Gulf of St. Lawrence and to provide science advice on stock status to fishery managers, decision makers and industry stakeholders. DESCRIPTION: The sea scallop research survey is conducted on CCGS MPerley (or chartered vessels) and has stratified random sampling. For each tow (or sample), data is recorded on tow, all specimens caught, geolocation, shell height frequency and biological samples. This monitoring program is currently on-hold. It will resume if a survey is deemed necessary to provide a new or updated science advice in the future. Stock status is currently (2024) in the critical zone. Rebuilding plan to follow. PARAMETERS COLLECTED: Catch number (biological), catch weight (biological), individual lengths (biological), age (biological), meat weight (biological). PHYSICAL SAMPLE DETAILS: A sub-sample of scallop shells is retained and analysed for age determination in the lab. SAMPLING METHODS: From 2012 to 2016, an annual, rotational, multispecies research survey program for scallop in the sGSL was conducted to obtain fishery independent indices of abundance, biomass estimates, and biological characteristics information (shell height, meat weight, sex, clappers). One section of a SFA or the SFA in its entirety was surveyed per year, with the exception of SFA 23 which was excluded because of the low scallop fishing effort reported from this area in recent years. From 2019 to 2023, annual surveys were conducted on the three major beds in the Northumberland Strait (West Point and Cape Tormentine in SFA 22, Pictou in SFA 24), using a similar methodology as the previous surveys. Methodology can be found in the Science Advisory Report and the Research Document listed in the citations list. USE LIMITATION: To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

Woodland caribou habitat potential within the provincial forest of central and northern Saskatchewan has been identified by Saskatchewan, using a forest ecosite geographic information system layer which has been mapped for the SK1 area. Download: hereCaribou habitat potential has been categorized into low, moderate and high classes based on the biophysical attributes of the Saskatchewan ecosite classification (McLaughlan et al., 2010) and their utility and function for caribou. Forest ecosites represent information about a site's tree species, plant-abundance and soil and site characteristics. Forest ecosite habitat potential ranks were assigned by individually evaluating the ecosite's potential to provide forage, refuge and calving habitat. Habitat potential refers to the ability or capability of a habitat type to support a wildlife species for its various life requirements. Potential does not consider the current state of the habitat (e.g., recently burned or harvested), but its optimal state.Habitat Potential Classes: Low habitat potential = 0 Moderate habitat potential = 1 High habitat potential = 2 

The documented occurrence data package contains 3 datasets that, in combination, help to provide generalized information about woodland caribou locations and survey areas in Saskatchewan. This information may assist users in their efforts to avoid or mitigate impacts to woodland caribou when operating in woodland caribou range. Generalized locations of caribou use have been provided to better reflect their large home ranges. Absence of a hexagon in an area should not be interpreted as absence of woodland caribou. Please read the Data Guide for important information about this product. Download survey boundaries, telemetry occurrence, and sightings/sign. Download the full package, including data guide here. The Woodland Caribou Documented Occurrence public data product is composed of three shapefiles/feature classes: 1. Woodland Caribou Occurrence - Sighting and Sign 2. Woodland Caribou Occurrence - Telemetry 3. Woodland Caribou Survey Boundaries The two occurrence datasets contain a grid of 18 sq km hexagons (tessellation). The inclusion of a hexagon in the dataset indicates that one or more animal sightings or sign, or telemetry points have been documented in that area. Importantly, lack of caribou occurrence (e.g. no hexagon) should not be interpreted as absence of woodland caribou. Rather, data may not have been collected in these areas or incidental or other observations have not been received.   The survey boundaries dataset displays the boundaries of woodland caribou surveys that were completed by or in collaboration with the Ministry of Environment from 2005 to 2024. Boundaries are from multiple sources, and include various types of surveys (fecal pellet collection or telemetry). These boundaries provide context when viewed alongside the woodland caribou occurrence datasets. We expect to see more occurrence locations in areas that have been surveyed. This information may provide context to areas with a seemingly higher number of occurrences.  For a full description of the data, please refer to the Data Guide document available for download on the Saskatchewan GeoHub.
