East Bay Regional Park District with ward boundaries, within the extent of Alameda County; boundaries have been updated to show 2011-2012 redistricting changes. Boundaries represent voting districts (i.e., district designation for each address) and therefore may align with parcel boundaries in cases where parcels (and sometimes residences) are divided by the true city/district boundary.

At the request of the East Bay Regional Parks District (EBPRD), Nomad Ecology (Nomad), Benson Bio Consulting (Shelly Benson), and Tukman Geospatial (project manager Brittany Burnett) conducted a fine-scale grassland vegetation mapping project on 11,000 acres of grasslands and low-cover shrublands in 16 parks owned and managed by East Bay Regional Parks District (EBRPD) in Alameda and Contra Costa counties. This project used field vegetation sampling and mapping to produce a fine-scale vegetation map (alliance and association level) to identify the composition and location of these native grassland vegetation types, so mapped polygons do not correspond with any imagery base. Areas mapped in the enhanced lifeform map as anything except upland herbaceous or non-native herbaceous were excluded from the matrix. These matrix polygons were incorporated into the final grassland map and flagged "Yes” in the field “Matrix Flag.”. The methods used for this vegetation sampling and mapping project are consistent with the Manual of California Vegetation and followed protocols established by CDFW VegCAMP and CNPS. This map was made in 2023.This fine scale grassland map represents native grasslands and low-cover shrublands throughout select East Bay Regional Parks District (EBRPD) lands – a 74-class grassland map with 2,805 polygons. The mapping was conducted in the spring-summer of 2023 and 2024. The map also includes a non-native matrix covering areas not mapped as native grasslands or low-cover shrublands. After field work concluded, field staff conducted a thorough quality assurance process, which involved checking for polygons under the 1/5-acre minimum mapping unit (MMU), overlapping polygons, and accurate data attribution.Spatial data for this project is also available on pacificvegmap.org. The report for this project is available here: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=228273

Communities in east Hudson Bay and James Bay are concerned about ecosystem changes observed in recent decades, particularly related to sea-ice conditions, and also about potential impacts of contaminants from long-range atmospheric transport and regional human activities. The Arctic Eider Society’s Community-Driven Research Network (CDRN) was established to measure and better understand large-scale cumulative environmental impacts in east Hudson Bay and James Bay. Building on CDRN collaborations and activities in five communities (Sanikiluaq, Kuujjuaraapik, Inukjuak, Umiujaq, Chisasibi), this Northern Contaminants Program (NCP) community-based project generated new information on metal bioaccumulation that provide a regionally integrated perspective on metal exposure in the marine environment of east Hudson Bay and James Bay.

As part of the NSTA's published 2018/19 Activity Plan, the NSTA is publishing a set of regional geological maps for the East Irish Sea and Cardigan Bay area of the UKCS. These maps represent the sixth set of deliverables from a 3 year contract with LR.

Watershed Stewards Program Corpsmembers and Scientists from the SF Bay Regional Water Quality Control Board created this StoryMap to visually demonstrate to the public the current and prior bacteria levels in local East Bay creeks. The purpose of this StoryMap is to represent up to date bacteria levels and give recommendations on whether the water levels are safe for contact. The creeks that are being sampled weekly are Baxter Creek and San Pablo Creek in Richmond, California and Sausal Creek, Peralta Creek, and Arroyo Viejo Creek in Oakland, California.

This part of DS 781 presents data for the faults for the geologic and geomorphic map of the Offshore of Monterey map area, California. The vector data file is included in "Faults_OffshoreMonterey.zip," which is accessible from http://dx.doi.org/10.3133/ofr20161110. The shelf north and east of the Monterey Bay Peninsula in the Offshore of Monterey map area is cut by a diffuse zone of northwest striking, steeply dipping to vertical faults comprising the Monterey Bay Fault Zone (MBFZ). This zone, originally mapped by Greene (1977, 1990), extends about 45 km across Monterey Bay (Map E on sheet 9). Fault strands within the MBFZ are mapped with high-resolution seismic-reflection profiles (sheet 8). Seismic-reflection profiles traversing this diffuse zone in the map area cross as many as 5 faults over a width of about 4 to 5 km (see, for example, figs. 3 and 5 on sheet 8). The zone lacks a continuous "master fault," along which deformation is concentrated. Fault length ranges up to about 20 km (based on mapping outside this map area), but most strands are only about 2- to 7-km long. Faults in this diffuse zone cut through Neogene bedrock and locally appear to minimally disrupt overlying inferred Quaternary sediments. The presence of warped reflections along some fault strands suggests that fault offsets may be both vertical and strike-slip. Specific offshore faults within the zone that are continuous with mapped onshore faults include the Navy Fault, Chupines Fault, and Ord Terrace Fault (Clark and others, 1997; Wagner and others, 2002). Carmel Canyon, a relatively straight northwest-trending arm of the Monterey Canyon system, extends through the southwestern part of the Offshore of Monterey map area. Carmel Canyon has three heads (Greene and others, 2002), two of which extend east and northeast into Carmel Bay within the map area; the third head extends southeast along the main canyon trend for about 3 km beyond the confluence with the heads in Carmel Bay. Carmel Canyon is aligned with and structurally controlled by the San Gregorio fault zone (Greene and others, 1991), an important structure in the distributed transform boundary between the North American and Pacific plates (see, for example, Dickinson and others, 2005). This Fault Zone is part of a regional fault system that is present predominantly in the offshore for about 400 km, from Point Conception in the south (where it is known as the Hosgri Fault; Johnson and Watt, 2012) to Bolinas and Point Reyes in the north (Bruns and others, 2002; Ryan and others, 2008). The San Gregorio Fault Zone in the map area is part of a 90-km-long offshore segment that extends northward from Point Sur (about 24 km south of the map area), across outer Monterey Bay to Point Año Nuevo (51 km north of the map area) (see sheet 9; see also, Weber and Lajoie, 1980; Brabb and others, 1998; Wagner and others, 2002). High-resolution seismic-reflection data collected across the canyon do not clearly image the San Gregorio Fault Zone, due largely to significant depth and steep canyon walls. Accordingly, we have mapped the 1,000- 1,300-m-wide fault zone largely on the presence of prominent, lengthy, geomorphic lineaments (sheets 1 and 2) and both geomorphic and lithologic contrasts across the fault. Faults were primarily mapped by interpretation of seismic reflection profile data (see OFR 2013-1071). The seismic reflection profiles were collected between 2007 and 2010.

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

The Natural Resource Management (NRM) Regions dataset was prepared for the purpose of reporting on the Australian Government's previous natural resource management program, Caring for our Country (2008-2013). The dataset was designed to cover all Australian territory where Caring for our Country projects might have taken place including major islands; external territories; state and coastal waters; in addition to the 56 NRM regions. This version of the data is an update and formalisation of the 'interim 2010' dataset (which was an interim update of the NRM Regions 2009 dataset- publicly released in Feb 09). Whilst the boundaries of NRM Regions are defined by legislation in some states and territories this dataset should not be used to represent legal boundaries in any way. It is an administrative dataset developed for the purpose of reporting and public information. It should be noted that from time to time the states and/or territories may revise their regional boundaries in accordance with local needs and therefore alterations to either the attribution or boundaries of the data may occur in the future. 'Caring for our Country commenced on 1 July 2008 and closed on 30 June 2013. It integrated delivery of the Australian Government's previous natural resource management programs: the Natural Heritage Trust, the National Landcare Program, the Environmental Stewardship Program and the Working on Country Indigenous land and sea ranger program. This is an administrative dataset developed for the purpose of reporting and public information. The dataset is not a legal boundary dataset and does not represent legal boundaries in any way. In total, this dataset represents 60 regions as set out below. They comprise 55 mainland regions administered by 54 NRM regional bodies (one region in QLD is jointly administered by two adjacent regional bodies) and seven islands (five administered by the Australian Government as external territories, and two administered by nearby mainland NRM regional bodies).

Dataset History

2006 Base Layer

The base layer for this dataset is the Natural Resource Management (NRM) Region Boundaries (formerly known as Natural Heritage Trust II (NHT2) Region Boundaries (2006)). This base layer has been perdiodically reviewed and built on to develop subsequent datasets.

The original 2006 base layer included an offshore component for regions in SA, TAS and QLD. Offshore components for the other States and the Northern Territories were created using Geoscience Australia's AMB 2006 coastal waters data. Mainland region boundaries were checked with all state and territory agencies resulting in changes to the internal mainland boundaries for QLD and WA. The amended boundaries were sourced from the relevant agency from these States.

Geoscience Australia's Geodata Coast 100K 2004 dataset was used for mainland state/territory borders. The AMB 2006 data was used to define the offshore boundaries between the States and the Northern Territory. Offshore boundaries between NRM Regions within a State were produced by extending region boundaries at 90 degrees to the state 100k coastline unless otherwise requested by state or territory agencies.

2009 version

This version included updates to: the internal boundaries within WA and Qld; the seaward extent of coastal regions, which were extended to the 3 Nm coastal waters limit for all States and the Northern Territory; the inclusion of more offshore islands (and coastal waters); and the addition of external territories and their 12 Nm territories sea.

The coastline has been removed from the data in line with the decision to extend all coastal NRM Regions to the outer limit of the adjacent coastal waters. It should be noted that the removal of the coastline means that islands lying within the outer limit of the Coastal Waters adjacent to the mainland are no longer depicted as separate features in the data. For example the many islands in Shark Bay WA are not displayed as separate entities in this dataset as they fall within the expanded (marine) extent of the Rangelands NRM Region in the new dataset. Users intending to create sub-continental scale maps to communicate locations of NRM regions boundaries are recommended to use additional layers containing coasts and near shore islands (as well as state/territory borders and major towns if required).

Not all coastal waters for the States and/or the Northern Territory have been included in the data. The primary consideration was whether land based activities might affect the adjacent waters. For the 2009 and subsequent datasets, coastal waters adjacent to the mainland and islands contained in the Geodata Coast 100K dataset are included. Significant islands include Macquarie Island (Tas) and Lord Howe Island (NSW).

Australia's External Territories (Heard and McDonald Islands, Cocos Keeling Islands, Christmas Island, Ashmore and Cartier Islands, and Norfolk Islands) have also been included in the 2009 and subsequent versions. The reporting region for these islands is the area within the outer limit of the 12 Nm Territorial Sea adjacent to each of these External Territories as sourced from the AMB 2006 data.

Specific issues relating to the development of the 2009 version for each State are described below:

WA- Data supplied from different WA regions contained overlaps around the Perth NRM. The Perth NRM confirmed that the NRM bodies work across neighbouring regions. As these boundaries remain ambiguous (and are not defined in any legislation) the Australian Government Land and Coasts settled on the boundaries in this dataset for the purposes of reporting.

NSW - Jervis Bay was added to the Southern Rivers NRM region after consultation with the Australian Government Land and Coasts NSW Team. Lord Howe Island was added to the NSW dataset as a part of the Northern Rivers NRM Region. The NSW Catchment Management Authority (CMA) Hawkesbury-Nepean, provided the marine NRM divisions between theirs and Central-Rivers, identifying that their northern regional boundary bisects Lion Island.

VIC - The Victorian Department of Sustainability and Environment (DSE) provided a state NRM dataset for this update. Their boundaries matched the pre-existing NRM Region Boundaries dataset, except for one small area between East and West Gippsland. Victoria agreed to use the pre-existing NRM boundaries in this area.

The addition of the 3Nm coastal waters component for Victoria presented a challenge in defining the offshore boundaries between Port Phillip and Westernport and the neighbouring NRM Regions of Corangamite and West Gippsland. The islands on the western shore of Port Phillip Bay in the vicinity of Queenscliff (Swan Island and Duck Island) and Swan Bay have been included in the Corangamite NRM region. From north to south the border between the Corangamite NRM region and Port Phillip and Westernport Bay NRM region is a line drawn from the eastern arm of Edwards Point to Swan Point, along the eastern shore of Swan Island and between the southern extremity of Swan Island to the eastern extremity of Point Queenscliff. The offshore boundary between these regions is a line drawn directly south from Point Lonsdale to the outer limit of coastal waters. Finally, the offshore boundary between Port Phillip and Westernport Bay and West Gippsland is a line drawn directly south from the town of San Remo to the outer limit of coastal waters.

Tas - The area of Coastal Waters adjacent to the Hogan Group of islands in Bass Straight is divided between Victoria and Tasmania. For the purpose of this dataset the entire area has been allocated to the North NRM region of Tasmania.

2010 Version

The major changes to the data for this dataset are that new NRM region boundaries for South Australia which came into effect on 1 July 2009 have been incorporated into the data; and, the data structure (attributes) have been modified.
