The COSEWIC Index of Area of Occupancy (IAO; also called Area of Occupancy, AOO by the IUCN) and Extent of Occurrence (EOO; IUCN as well) are metrics used to support status assessments for potentially endangered species.
cosewic_ranges( df_db, record = "record_id", coord_lon = "longitude", coord_lat = "latitude", species = "species_id", iao_grid_size_km = 2, eoo_p = 0.95, filter_unique = FALSE, spatial = TRUE )cosewic_ranges( df_db, record = "record_id", coord_lon = "longitude", coord_lat = "latitude", species = "species_id", iao_grid_size_km = 2, eoo_p = 0.95, filter_unique = FALSE, spatial = TRUE )
df_db |
Either data frame or a connection to database with
|
record |
Character. Name of the column containing record identification. |
coord_lon |
Character. Name of the column containing longitude. |
coord_lat |
Character. Name of the column containing latitude. |
species |
Character. Name of the column containing species identification. |
iao_grid_size_km |
Numeric. Size of grid (km) to use when calculating IAO. Default is COSEWIC requirement (2). Use caution if changing. |
eoo_p |
Numeric. The percentile to calculate the convex hull over. Defaults to 0.95 for a 95% convex hull to ensure outlier points do not artificially inflate the EOO. Note that for a final COSEWIC report, this may not be appropriate. Set to 1 to include all points. |
filter_unique |
Logical. Whether to filter observations to unique
locations. Use this only if there are too many data points to work with.
This changes the nature of what an observation is, and also may bias
EOO calculations if using less than 100% of points (see |
spatial |
Logical. Whether to return sf spatial objects showing
calculations. If |
Note that the while the IUCN calls this metric AOO, in COSEWIC, AOO is actually a different measure, the biological area of occupancy. See the Distribution section in 'Instructions for preparing COSEWIC status reports' for more details.
By default the EOO is calculated only using the inner 95% of points (based on
distance to the centroid). This is to ensure that a first-pass of the EOO
does not reject a species from consideration if there are any outlier
observations. However, for a final COSEWIC assessment report, it is likely
better to carefully explore the data to ensure there are no outliers and then
use the full data set (i.e. set eoo_p = 1).
The IAO is calculated by first assessing large grids (10x large than the specified size). Only then are smaller grids created within large grid cells containing observations. This speeds up the process by avoiding the creation of grids in areas where there are no observations. This means that the plots and spatial objects may not have grids over large areas lacking observations. See examples.

by refers to the combination of columns which are used to detect
missing values. By default SamplingEventIdentifier is used. Otherwise
users can specify their own combination of columns.
If species is supplied, all records will be used to determine observation
events, but only records (zero-filled or otherwise) which correspond to a
species in species will be returned (all others will be omitted). Note
that records where species_id is NA (generally for 0 counts for
presence/absence), will be converted to a list of 0's for the individual
species.

The akn_level column describes the level of data access for that collection
(see descriptions online).
The access column describes the accessibility of a collection for a given
username (or no access if no username supplied). See the section on Access
and request_ids for more details.
Data frame
All public data is available with a username/password
(sign up
for a free NatureCounts account). However, to access private/semi-public
projects/collections you must request access. See the Access and
request_ids section for more information.
species)Numeric species id codes can determined from the functions
search_species() or search_species_code(). See also the article on
species codes
for more information.
doy)The format for day of year (doy) is fairly flexible and can be a whole
number between 1 and 366 or anything recognized by
lubridate-package's ymd()
function. However, it must have the order of year, month, day. Note that
year is ignored when converting to day of year, except that it will result
in a 1 day offset for leap years.
region)Regions are defined by codes reflecting the country, state/province,
subnational (level 2), Important Bird Areas (IBA), and Bird Conservation
Regions (BCR) (see search_region() for codes). They can also be defined
by providing specific UTM squares to download or a bounding box area which
specifies the min/max longitude and min/max latitude (bbox). See the
article on regional filters
for more information.
request_idsAccess to a data collection is either available as "full" or "by request".
Use nc_count(username = "USER", show = "all"), to see the accessibility of
collections.
"Full" access means that data can be immediately requested directly through
the naturecounts R package. "By request" means that a request must be
submitted online and
approved before the data can be downloaded through naturecounts.
This means that there are two types of data requests: ones made through this
naturecounts R package (API requests) and those made through the online
Web Request Form (Web
requests). Every request (from either method) generates a request_id which
identifies the filter set and collections requested. Details of all of
requests can be reviewed with the nc_requests() function.
To download data with "full" access, users can either specify filters, or if
they are repeating a download, can use the request_id from nc_requests().
Otherwise, if the user doesn't have "full" access, they must supply an
approved request_id to the nc_data_dl() function (e.g.,
nc_data_dl(request_id = 152000, username = "USER")). Use nc_requests() to
see request_ids, filters, and approval status.
Requests for "full" access to additional collections can be made online through the Web Request Form by checking the "Full access?" box in Step 2 of the form.

Download data records from various collections filtered by various options.
In order to ease the load on the server, note that only three of
collections/project_ids, species, years, doy, region, and
site_type can be used in any one request. See the vignette for filtering
your data after download for more options:

All public data is available with a username/password
(sign up
for a free NatureCounts account). However, to access private/semi-public
projects/collections you must request access. See the Access and
request_ids section for more information.
species)Numeric species id codes can determined from the functions
search_species() or search_species_code(). See also the article on

for more information.
doy)The format for day of year (doy) is fairly flexible and can be a whole
number between 1 and 366 or anything recognized by

region)Regions are defined by codes reflecting the country, state/province,
subnational (level 2), Important Bird Areas (IBA), and Bird Conservation
Regions (BCR) (see search_region() for codes). They can also be defined
by providing specific UTM squares to download or a bounding box area which
specifies the min/max longitude and min/max latitude (bbox). See the
article on regional filters
for more information.
fields_set and fields)By default data is downloaded with the minimum set of fields/columns.
However, for more advanced applications, users may wish to specify which
fields/columns to return. The Bird Monitoring Data Exchange (BMDE) schema
keeps track of variables used to augment observation data. There are
different versions reflecting different collections of variables which can
be specified for download in one of four ways:
fields_set can be a specific shorthand reflecting a BMDE version:
core, extended or minimum (default). See meta_bmde_versions() to see
which BMDE version the shorthand refers to.
fields_set can be default which uses the default BMDE version for a
particular collection (note that if you download more than one collection,
the field sets will expand to cover all fields/columns in the combined
collections)
fields_set can be the exact BMDE version. See meta_bmde_versions()
for options.
fields_set can be custom and the fields argument can be a
character vector specifying the exact fields/columns to return. See
meta_bmde_fields()) for potential fields values.
Note that in all cases there are a set of fields/columns that are always
returned, no matter what fields_set is used.
request_idsAccess to a data collection is either available as "full" or "by request".
Use nc_count(username = "USER", show = "all"), to see the accessibility of
collections.
"Full" access means that data can be immediately requested directly through
the naturecounts R package. "By request" means that a request must be
submitted online and
approved before the data can be downloaded through naturecounts.
This means that there are two types of data requests: ones made through this
naturecounts R package (API requests) and those made through the online
Web Request Form (Web
requests). Every request (from either method) generates a request_id which
identifies the filter set and collections requested. Details of all of
requests can be reviewed with the nc_requests() function.
To download data with "full" access, users can either specify filters, or if
they are repeating a download, can use the request_id from nc_requests().
Otherwise, if the user doesn't have "full" access, they must supply an
approved request_id to the nc_data_dl() function (e.g.,
nc_data_dl(request_id = 152000, username = "USER")). Use nc_requests() to

All public data is available with a username/password
(sign up
for a free NatureCounts account). However, to access private/semi-public
projects/collections you must request access. See the Access and
request_ids section for more information.
request_idsAccess to a data collection is either available as "full" or "by request".
Use nc_count(username = "USER", show = "all"), to see the accessibility of
collections.
"Full" access means that data can be immediately requested directly through
the naturecounts R package. "By request" means that a request must be
submitted online and
approved before the data can be downloaded through naturecounts.
This means that there are two types of data requests: ones made through this
naturecounts R package (API requests) and those made through the online
Web Request Form (Web
requests). Every request (from either method) generates a request_id which
identifies the filter set and collections requested. Details of all of
requests can be reviewed with the nc_requests() function.
To download data with "full" access, users can either specify filters, or if
they are repeating a download, can use the request_id from nc_requests().
Otherwise, if the user doesn't have "full" access, they must supply an
approved request_id to the nc_data_dl() function (e.g.,
nc_data_dl(request_id = 152000, username = "USER")). Use nc_requests() to
see request_ids, filters, and approval status.
