Sam Friedman, U.S. Fish and Wildlife Service, Botanist 20230531 vector digital data We mapped and assessed areas of remaining undeveloped mounded landform habitat across the Rogue River Valley, Oregon, using lidar surface topography and aerial imagery, to support US Fish and WIldlife Service recovery efforts for vernal pool and vernal wetland species. Mounded landform in the Rogue River Valley is strongly associated with vernal pool or vernal wetland habitats suitable for ESA-listed recovery species: vernal pool fairy shrimp (Branchinecta lynchi), large-flowered woolly meadowfoam (Limnanthes pumila ssp. grandiflora), and Cook's desert parsley (Lomatium cookii). Mounded landform was identified by a systematic visual search of lidar bare-earth hillshade coverage (composite of 2009, 2011, and 2015 DOGAMI data) and recent aerial imagery (May 2016 - October 2020) in ESRI GIS and Google Earth; limited field checks conducted in 2022 were used to inform our remote sensing interpretation. Areas of discernable remaining mounded landform were mapped across all soil types below 3000 ft elevation; on Agate-Winlo soils (Jackson County, OR, soil map) we also mapped any remaining undeveloped areas, even where no mounded landform was detected. Aerial imagery and lidar surface topography (reprocessed to 1 ft resolution) were used to visually classify the condition and characteristics of each habitat polygon (see attribute definitions below), and hydrologic modeling on the high resolution lidar DEM was used to estimate the extent of vernal pool and ephemeral flow wetlands (see metrics below). This mapping identifies potential remaining vernal pool / wetland habitat but has not been systematically verified with site or species surveys, or observations of surface inundation; this mapping is not based on or intended to be interpreted as wetland delineation. See the metadata attribute information for full definitions of the attribute fields and their domain values. These polygons identify potential remaining mounded vernal pool and vernal wetland habitat as of 2020 in the Rogue River Valley, Jackson County, Oregon. Mapping is based on remote sensing (lidar surface topography and aerial imagery) and includes all detected areas of mounded landform within the Rogue River Valley and surrounding foothills below 3000 feet elevation. Mounded landform in the Rogue River Valley is strongly associated with vernal pool or vernal wetland habitats suitable for ESA-listed recovery species: vernal pool fairy shrimp (Branchinecta lynchi), large-flowered woolly meadowfoam (Limnanthes pumila ssp. grandiflora), and Cook's desert parsley (Lomatium cookii). This habitat mapping was developed to aid US Fish and Wildlife Service recovery efforts for these species and habitat protection efforts by public agencies or private conservation organizations. Attributes include landform condition, characteristics, and hydrologic modeling metrics. See the Description section below for additional information and attribute definitions.

Each polygon identifies a continuous area of mounded landform in similar condition. Areas of discernable mounded landform were comprehensively mapped across all soil types below 3000 feet elevation; on Agate-Winlo soils we also mapped any remaining undeveloped areas, even where no mounded landform or patterned ground was detected. USFWS OBJECTID Internal feature number. Esri Sequential unique whole numbers that are automatically generated. Shape Feature geometry. Esri Coordinates defining the features. landform The degree of current mounded landform expression visible in lidar hill shade coverage and aerial imagery. Identifies the visual distinctiveness of mound and basin topography and relative elevations. Landform categories do not discern between natural or anthropogenic causes of condition. Polygons may have small inclusions of alteration, development, or a different landform category covering < 5% of the area. These are best-fit categories for a continuous range of landforms. USFWS Strong Landform clear and distinct with strong patterning and substantial elevation differences between mounds and basins. Natural landform with little or no obvious signs of topographic alteration - but not all minimally altered landforms are Strong, because some areas have naturally limited topography. USFWS Moderate Landform distinct but with lower visual clarity of pattern and less apparent difference in elevation between mounds and basins. The landform can appear natural or altered; alteration can range from continuous across the polygon to an uneven mix of type and intensity at a smaller scale than warrants separate polygons. USFWS Weak Landform present across the polygon but mound and basin forms are not clear and distinct and have little apparent difference in elevation between mounds and basins. The landform can appear natural or altered; alteration can range from continuous across the polygon to an uneven mix of type and intensity at a smaller scale than warrants separate polygons. Incomplete leveling is a typical alteration. USFWS Trace Landform is discernable only as faint traces of mounded topography in lidar hill shade and/or as mound and basin patterning in soils and vegetation visible in recent aerial imagery. Applies mainly to intensely altered Agate-Winlo soils and is evidence that natural hardpan and native soils may remain, with potential for habitat restoration. Can also occur on less intensely altered areas with naturally marginal landform expression or transitional zones. USFWS Absent Specific to Agate-Winlo soil sites lacking any evidence of mound and basin landform or soil and vegetation patterning. Applies primarily to undeveloped but intensely altered sites but can also occur on light to moderately altered naturally marginal sites that likely did not have clearly expressed landform prior to disturbance. USFWS RFA_Name Identifies the Recovery Focal Area that the mounded landform habitat polygon is included in - or "Outside of" for polygons not included in Recovery Focal Areas. USFWS alteration The intensity of anthropogenic physical alteration of the natural mounded landform. Identifies the apparent degree of human-caused topographic disturbance as evident in lidar hill shade, aerial imagery, and hydrology modeling interpreted in the context of known land-use history. Alteration categories do not identify the specific cause or type of disturbance, only the apparent resulting intensity of change to the landform (except for known restoration areas). Polygons may have small inclusions of development or a different alteration category covering < 5% of the area. USFWS Light Landform shows little or no direct evidence of physical alteration. This is the lowest category of alteration because no sites are known to remain fully intact. A light alteration intensity does not necessarily correspond to strong landform expression; some habitat areas appear to have naturally limited landform. USFWS Moderate Clear evidence of substantial alteration across the area. The landform may remain distinct, but with diminished topographic form and clarity, or may be weak to absent for naturally limited landform. Evident disturbance may be continuous and systematic or an irregular mix of type and intensity at a finer scale than warrants separate polygons. USFWS Heavy Clear evidence of intense topographic alteration across the area. Mounded landform may remain present but is obscured by widespread disruption of topographic pattern. Disturbance may be continuous and systematic or an irregular mix of type and intensity at a finer scale than warrants separate polygons; can include limited impacts from added off-site soils, excavation, or small artificial water bodies. USFWS Leveled Intentional leveling of the ground surface has erased the mound and basin landform or diminished it to a weak or trace expression. Little or no relative elevation difference between mounds and basins; the area may appear completely flat or have faint scattered remnant mound forms. This disturbance can be smooth or rough-graded but is characteristically systematic and continuous across the polygon. Applies mainly to sites on Agate-Winlo soils. USFWS Restored The site is known to have been intentionally re-contoured to restore mound and basin landform and hydrologic function for ecological objectives and/or wetland mitigation. This category does not assess the effectiveness of the grading in restoring natural landform of functional habitat, and includes some "restored" sites with topography that is very different from natural Rogue Valley mounded landform. Effectively restored sites may not be easily distinguished from natural landform in lidar or aerial imagery; additional information on site history was used to identify the current topography as the result of restoration grading. USFWS Transformed Sites with no remaining landform where intense topographic alteration has removed, added, or rearranged soils without major development of structures or infrastructure. Applies primarily to artificial ponded or excavated areas on historic Agate-Winlo soils where vernal wetland habitat may remain or be restorable. USFWS SoilName_dom The primary soil type covering the majority of the polygon area. Sourced from the Jackson County Soil Survey map. USFWS MoundForm Descriptive geomorphic categories of mound and basin landform. Categories differ by the characteristic size, shape, coverage, and spatial arrangement of mounds as apparent in lidar hill shade and aerial imagery. Geomorphology is strongly linked to soil type, slope, hydrology, and topographic position. Cannot be consistently identified for Leveled areas where landform expression is lost (Pattern or Absent) – but can often be inferred on these areas based on adjacent landform. Descriptive geomorphic categories of mound and basin landform. Categories differ by the characteristic size, shape, coverage, and spatial arrangement of mounds as apparent in lidar hill shade and aerial imagery. Geomorphology is strongly linked to soil type, slope, hydrology, and topographic position. Cannot be consistently identified for Leveled areas where landform expression is lost (Pattern or Absent) – but can often be inferred on these areas based on adjacent landform. USFWS Continuous Large, regularly spaced generally oval to oblong mounds covering most of the land surface. Typical of flat or gently sloping Agate-Winlo valley bottom soils. USFWS Sparse Relatively small, regularly spaced oval to oblong mounds occupying approximately 50% or less of the land surface. Typical of low to moderate slope outlying clay soils on valley margins. USFWS Irregular Mounds naturally vary in size, shape, and spatial arrangement. Typical of outlying soils with shallow bedrock and uneven terrain with low to moderate slope. USFWS Linear Relatively small mounds arranged in elongated rows or linked chains oriented with the slope. Typical of outlying shallow soils with moderate to steep slopes. USFWS Drainage Mounds relatively large and elongated, often with an interlinked or braided arrangement following a converging pattern of drainage flows. Typical of slope and hydrologic transitions across a range of soil types on low to moderate slopes. USFWS Unknown Mound form no longer identifiable due to absence of landform. USFWS TreeCover Identifies the current cover of woody vegetation as trees within the polygon. Estimated from current 2020 aerial imagery in 25% cover classes: 0, < 25%, 25 – 50%, 50 – 75%, >75%. This provides information on the type of habitat and likely vegetation communities, and may indicate differences in hardpan structure, drainage, and pool inundation – especially at higher levels of tree coverage. Inferences from visual assessments are limited by past clearing and land use confounding natural and altered conditions. USFWS ShrubCover Identifies the current cover of shrubs, within the polygon. Estimated from current 2020 aerial imagery in 25% cover classes: 0, < 25%, 25 – 50%, 50 – 75%, >75%. This provides information on the type of habitat and likely vegetation communities, and may indicate differences in hardpan structure, drainage, and pool inundation – especially at higher levels of tree coverage. Inferences from visual assessments are limited by past clearing and land use confounding natural and altered conditions. USFWS LandUse The current primary land use associated with each polygon, grouped into broad categories based on relevance to habitat conservation and species recovery. Land use was visually assessed from 2020 aerial imagery and informed by existing zoning, ownership, and land use public information, but is not sourced from tax records, zoning categories, or owner-provided information. These are estimates only, with accuracy limited by detection uncertainty, recent land use changes, and multiple-use areas. USFWS AgIrrigated Irrigated intensive agriculture, including row crops, irrigated pasture or hayfield, nursery stock, orchard, or vineyard. Identified as distinct unseasonal green vegetation, visible crop rows, or freshly tilled fields in recent aerial imagery. USFWS AgNonIrrigated Non-irrigated intensive grazing land, hayfields, or fallow fields on agriculturally managed land. Does not include open range grazing. USFWS OpenLand Undeveloped public or private land in a generally natural condition with no apparent intensive land management. Includes grasslands and woodlands, dispersed recreation and natural areas, open range grazing land, and non-agricultural vacant land that is not in residential, commercial, or industrial settings. USFWS Conservation Private or public land known to be primarily managed for habitat conservation. Includes nature preserves, conservation easements, wildlife areas, and wetland mitigation land not managed for active use by the public. Similar to open land and identified using information on land ownership and status. USFWS PublicPark Designated natural areas or open space on public land specifically managed for focused public use and low-impact recreation. Can include limited structures. USFWS Residential Private properties with existing homes or vacant lots within rural or urban residential areas. Can include large private lots and limited secondary uses. USFWS CommIndustrial Private land in active commercial or industrial use or vacant lots in areas zoned or planned for those uses. Includes urban or rural industrial facilities, aggregate removal, business and shopping areas, and commercial recreational areas. USFWS PublicFacility Public land associated with developed facilities for a wide range of uses. Includes education, transportation, public utilities and services, sports or intensive recreation, cemeteries, and government facilities. Does not include nature parks. USFWS PolygonID Sequential numeric unique identifier for each habitat polygon. USFWS acres GIS-calculated acres within each habitat polygon, US Survey Acres. USFWS PostLidar Value of "1" identifies polygons where the landform appears to have been significantly altered since the most recent available DOGAMI lidar coverage at the time of mapping. Our lidar hill shade coverage and hydrology modeling will not be accurate for these polygons. USFWS Soils_all List-format field including all overlapping soil types for each polygon; with soil names and mapped extents sourced from Jackson County Soil Survey map layer. USFWS Elev_mean Mean elevation in feet of the polygon. Sourced from lidar DEM. Given elevational gradients of climate and plant communities, no landform occurrences were mapped above 3,000 feet. USFWS Slope_mean Mean percent slope within the polygon, as modeled on high-resolution lidar surface DEM. USFWS Pools_Ac Potential number of distinct vernal pool basins per acre within the polygon, calculated from hydrologic modeling on high-resolution lidar surface DEM. USFWS Pool_Avg_ft2 Average modeled pool area (square feet) within the polygon, calculated from hydrologic modeling on high-resolution lidar surface DEM. USFWS Pool_Avg_ft3 Average modeled pool basin volume (cubic feet) within the polygon, calculated from hydrologic modeling on high-resolution lidar surface DEM. USFWS Pools_PctArea Percent of total polygon area covered by vernal pool basins, as modeled on high-resolution lidar surface DEM. USFWS Depth_MaxAvg_in Average maximum depth in inches of modeled pools in polygon, as modeled on high-resolution lidar surface DEM. USFWS Shape_Length Length of feature in internal units. Esri Positive real numbers that are automatically generated. Shape_Area Area of feature in internal units squared. Esri Positive real numbers that are automatically generated. 20231129 U.S. Fish and Wildlife Service Sam Friedman Botanist mailing and physical
