Q & A 2 Herbicide Application - Lakeview District, OR

140L4323Q0195

Question 1 corrects an error in Question 6 of the previous Q&A.

Q1: An error was noted for Question 6 on the previous Q&A document. On question number 6 for a carrier of water at 5oz/AC would put you off label for the imazapic treatment. I think what you are wanting is 5 gallons per acre and 10 gallons per acre, not ounces.

A1: Correct, A minimum of 5 gallons/ac of water added for burned areas and doubled to 10 gallons/ac. of water for unburned areas.

Q2: Can you please confirm the total acres anticipated? to be sprayed for 2023 are lines 001 (1132ac.), 002 (1,455ac.), and 004 (3,100ac.) for total of 5,687 total acres for fall of 2023?

A2: Correct

Q3: Line 006 has error, states “fall 2004” please confirm this is “fall 2024”, not 2025, or subsequent.

A3: Line 006 should state, “Option may be exercised if a fire occurs in 2024”

Q4: Can I also get an updated shapefile for the proposed acres? The one on Beta sam only yielded 4606 acres.

A4: Additional Shape files are attached. However, finalized shape files will be released to the awardee.

Item 001 Large Scale Annual Grass Herbicide Application Projects - Harpold Ridge 1 (188 ac.) & 2 (63 ac.), Windy Ridge 4, (188 ac.) Horton northwest (588 ac.) - Klamath Falls Field Office.

Special dates to avoid treatment due to opening weekends of hunting seasons will apply.

The location of these non-contiguous project units are within the KFFO, Lakeview District BLM and are approximately 50 miles from the town of Klamath Falls.

The project areas are within previous juniper removal units and vary in size (see above acres) and all are within BLM managed lands. Native vegetation recovery within these sagebrush restoration units are threatened by annual grasses invasion. The potential for type conversion to an annual grass dominated area is extremely likely if left untreated.

The treatment of BLM managed lands will occur in the early fall (August/September 2023) to prevent the germination and establishment of invasive annual grasses including North African grass (Ventenata dubia), medusahead rye

(Taeniatherum caput-medusae), and cheatgrass (Bromus tectorum) within the burned perimeter. See attachment 2

Item 002 Van Meter Fire (1,455 ac.) - Annual Grass Herbicide Application Treatments-Klamath Falls Field

Office.

The Van Meter Fire was ignited by lightning on 9/7/2022 within the Van Meter Flat area approximately 8 miles southeast of the town of Klamath Falls in Klamath County Oregon. 1,455 acres (55%) of the burned area is located on BLM managed land in Klamath County, Oregon while 1,178 ac. (45%) is located on private land. The terrain in the burned area varies between mostly forested northeast aspect rocky steep slopes and grass-shrub semi-arid rangelands on southwest aspect slopes at approximately 4,500 feet elevation and receives approximately 15” of annual precipitation. The vegetation is dominated by western juniper, ponderosa pine, mountain big sagebrush and low sagebrush communities. The fire affected habitat for sagebrush steppe associated wildlife species including pronghorn, and mule deer. The area burned by the fire was dominated by ponderosa pine (Pinus ponderosa), western juniper

(Juniperus occidentalis), mountain big sagebrush (Artemisia tridentata), low sagebrush (Artemisia arbuscula), and antelope bitterbrush (Purshia tridentata) intermixed with birch-leaf mahogany (Cercocarpus betuloides), serviceberry

(Amelanchier utahensis), and Klamath plum (Prunus subcordata), which may resprout post-fire, in addition to curl-leaf mountain mahogany (Cercocarpus ledifolius), and bittercherry (Prunus emarginatata), which are not likely to resprout post-fire especially in areas with high vegetation mortality and high soil burn severity. These high severity areas will likely have seed that was killed in the soil seed bank, and these areas not likely to recover naturally without seeding and herbicide treatments. The southern portion of the fire burned in more of a mosaic with some low/unburned vegetation present while the northern portion had more moderate and high fire severity and vegetation mortality.

Associated forb species that were impacted by the Van Meter Fire include sulfur buckwheat (Eriogonum umbellatum), arrowleaf balsamroot, Oregon sunshine (Eriophyllum lanatum), yarrow (Achillea millefolium), and perennial bunchgrasses including Sandberg’s blue grass (Poa secunda), squirreltail (Elymus elymoides), Idaho fescue (Festuca idahoensis), and bluebunch wheatgrass (Pseudoroegneria spicata).

Invasive weeds that exist within and adjacent to the burned area include: musk thistle (Carduus nutans), bull thistle

(Cirsium vulgare), Scotch thistle (Onopordum acanthium) and invasive annual grasses including medusahead rye

(Taeniatherum caput-medusae), Japanese brome (Bromus japonicus), North Africa grass (Ventenata dubia) and cheatgrass (Bromus tectorum)). These invasive weeds pose a threat to native vegetation recovery and re-establishment within the fire perimeter. In addition, suppression-related activities adjacent to the fire including dozerlines, staging areas, safety zones, and drop points that created additional disturbance likely to exacerbate the spread of invasive weeds within the Van Meter Fire.

Item 003 Annual Grass Herbicide Application Project Lorella Gale (450 ac.) - Klamath Falls Field Office.

The location of this project unit is within the KFFO, Lakeview District BLM and are approximately 50 miles from the town of Klamath Falls.

The project area is within previous juniper removal units and is within BLM managed lands. Native vegetation recovery within this sagebrush restoration unit is threatened by invasive annual grasses invasion. The potential for type conversion to an annual grass dominated area is extremely likely if left untreated.

The treatment of BLM managed lands will occur in the early fall (August/September 2024) to prevent the germination and establishment of invasive annual grasses including North African grass (Ventenata dubia), medusahead rye

(Taeniatherum caput-medusae), and cheatgrass (Bromus tectorum) within the burned perimeter. See attachment 2

Item 004 Lakeview Field Office Aerial Annual Grass Treatments

This project area, Clover Flat, is approximately 20 miles north of Lakeview, and within the Lakeview District BLM

Lakeview Field Office, Lake County, where an estimated 3,100-acre herbicide treatment is needed as an option if funding become available.

The project area is within a previously treated medusahead rye grass (Taeniatherum caput-medusae) site where recent field observations have documented the early stages of a conversion to an annual grass dominated area. If left untreated, the meadusahead infested area is likely to expand. Well established medusahead communities have low plant species diversity and have low value for wildlife habitat. Meadusahead is slow to invade late seral rangeland which means that the rangeland needs to be managed for high species diversity and given ample time for recovery.

The treatment of the BLM managed lands will occur in the fall 2023.

The objective of this project will be to apply herbicide to manage and suppress meadusahead to prevent its spread and minimize its negative impact on native plant communities, wildlife habitats, and livestock grazing areas. Controlling meadusahead rye helps to maintain biodiversity and preserve the ecological balance in affected ecosystems. Final maps and shapefiles will be provided prior to implementation.

Item 006 (Option) Klamath Falls field Office Post-fire Annual Grass Herbicide Application Treatments

The Post-fire restoration project area(s) will be within the Lakeview District BLM within the KFFO, Klamath County.

An estimate of up to 2,500 acres is anticipated for herbicide treatment needs as an option in the event that a wildfire occurs. Typically, wildfires occur on the Lakeview District in the late summer and fall/winter. Seeding is necessary that same year however, herbicide for annual grasses typically is done an entire year later due to contract deadlines and these unforeseen natural disasters. It would be useful to have this option in place for such events as wildfire.

The objective of this project will be to apply herbicide across a large area while minimizing disturbance from wheeled vehicles, to prevent invasive annual grass seed from germinating and becoming established. By restoring native species to the landscape, the invasive annual grass species will likely be reduced and be replaced by locally adapted, genetically appropriate native species. The goal is to restore the sagebrush-steppe ecosystems by increasing biodiversity and enhancing resiliency on public lands over time.

Option may be exercised if a fire occurs in 2024
