Project Title Post Fire Seed Collection in the Southern Blue Mountains Malheur National Forest

General Information

1.0 Background and Purpose

Seed collection service. The work scope includes locate and map collection sites of native forb, grass, and shrub species identified in table 2.2 below, then collect desired quantities of mature seed. After identification of the collection sites, and determination that the seed is ripe, filled out, and has not been predated by insects or disease, the Contractor shall collect the maximum specified quantities of seed from these areas, “rough” clean the seed according to task order specifications in Table 3.3, and package and deliver the seed to Contracting Officer’s Representative (COR) by October 15th of the collection year (see below for specific info on fleshy fruits). The estimated contract time for this project is 16 Sep 2025 to 30 Nov 2026 with potential to execute an option period 1 May 2026 to Nov 2027.

1.1 Description

The seed shall be collected from Forest Service land within the southern portion of the Blue Mountains Ecoregion (figure 1) in Provisional Seed Zones 15-20 F°/ 3-6 (base contract) and if an option year is exercised, Provisional Seed Zone 20-25 F°/ 3-6.

2.1 Definitions

Provisional Seed Zone PSZ- delineate areas of climatic similarity within Ecoregions. Transferring seeds within zones reduces the risk of maladaptation. In provisional seed zone nomenclature, the first part of the name indicates the range of minimum winter temperature for each zone and was determined as the minimum value per zone from December through February and was classified into 5°F bands. Thus 20-25 F° means that within this seed zone, the minimum temperatures from December to February is within this range. The second part of the seed zone (3-6) is an indication of the aridity within a seed zone. Higher values indicate more arid environments.

Contractor Requirements

3.0 Performance Tasks

3.1 General

3.1a This is a non-personal services contract. The contractor shall be fluent in the taxonomy and identification of native plants of the southern Blue Mountains and experienced with seed collection. They are to furnish all labor, materials, equipment, transportation, and any incidentals necessary for locating, monitoring, and collecting seed from the collection areas and not listed as government furnished property. The contractor must provide GPS equipment to accurately find seed zones and document seed collection sites.

3.1. b. Contractor Project Plan: The Contractor shall develop and maintain a project plan to ensure services are performed in accordance with this PWS. At a minimum the plan shall include the contractor’s technical approach and monthly milestone down to the CLIN level, and any planned sub-contracting. The work plan will be submitted to the COR within fourteen (14) days from the date of award. Deliverable 01. The Contracting Officer may direct modification(s) to the contractor’s work plan to address performance issues.

The Contract Manager or alternate shall be available during the Government's regular working hours.

The Contract Manager and contact data shall be provided to the COR within 14 days after contract award. Deliverable 02

3.2 Seed collection site and mapping Standards

(a) The Contractor shall locate suitable collection sites for obtaining the specified quantities of seed for each subitem. The Contractor shall allow enough time prior to seed collection for locating suitable collection sites.

Seed collection sites shall meet the following criteria:

(1) Seed collection sites shall be within the Southern Blue Mountain ecoregion and in PSZ 15-20 F°/ 3-6 for the base year contract and PSZ 20-25 F°/ 3-6 for the option year (See Figure 1 and table 2.2).

(2) To prevent contamination in collections, sites shall be free of infestations of plants listed as noxious by the Oregon Department of Agriculture (See “A & B” weed lists, Appendix A) as well as invasive grasses (Poa bulbosa, Bromus tectorum, and Ventenata dubia). If collection sites contain significant enough quantities of weedy plants that it increases risk of target seed collection contamination, alternative locations must be utilized.

(3) Collection sites should not include areas burned in the last three years. Information on those areas can be shared at the pre-work meeting.

(4) For some subitems, more than 5 collection sites may be required to obtain the specified quantities of seed. Sites should be discontinuous areas at a minimum of ¼ mile between populations.

(5) Each collection site shall be described and documented on the Potential Collection Site form (Attachment 4) and summarized on the included Summary Table (Attachment 5). Seed collection sites shall be numbered sequentially and GPSd as polygons. Spatial data can be submitted as ArcGIS shapefiles, AGOL feature service, KML, or Garmin gpx file types.

Naming conventions allow the data to be matched to the Individual Site Seed Collection Forms (Attachment 2) .

(6) The site identification code shall include the abbreviated genus and species code (e.g. Bromus carinatus = BRCA5)*, the task order subitem code, and the collection site number (e.g.

BRCA5-1-001).

(7) The location description on either the Arc GIS layer file or the Individual Site Seed Collection Form (Attachment 2) shall consist of enough information to enable an inspector to relocate the site, including GPS coordinates of each collection site in latitude and longitude in decimal degrees. Digital polygons should represent the entire area where collection occurs.

Accuracy should be better than 150 feet.

Standard:

(1) That seed collection sites are identified on GPS.

(2) That all required collection records are legible and accurate, and complete.

(3) That GPS coordinates are accurate within 150 feet.

(a) Changes to the target species or PSZ may be considered if biological challenges of a particular species prevent viable seed production in the collection year. This information will need to be communicated to the COR and species substitutes decided with them.

(b) Collections shall be conducted in a manner that does not damage existing vegetation. No more than 50 percent of the seed crop at each site shall be collected of each species.

(c) There must be at least two (2) sites for each species to collect the total amount of rough cleaned seed needed and to increase genetic diversity within each seed lot. The Contractor shall notify the COR 2 days prior to each site visit.

(d) The Contractor shall submit a work plan schedule to the COR for approval before the commencement of work. The work plan shall include each of the following:

(1) Contractor shall notify COR when species is becoming ready to collect, approximately 7 days prior to collection or shorter window if agreed upon with the COR.

Note: Multiple trips to sites may be required to determine when the seed is mature.

(2) A short description of the methods to be used to collect, rough clean, and store seed/fruit for each species.

(e) Plants that seed is collected from should appear healthy and vigorous and should not show any signs of disease.

(f) Seed shall be visually sound and sufficiently mature to be viable. Seed is considered sound when the embryo is developing normally and there is no evidence of insect, disease, climatic, or other types of damage. Seed maturity in plants with fleshy fruits often corresponds with changes in taste, odor, texture, or color (e.g., color changes from green to red, blue, purple or white). Fruits whose seeds are wind-dispersed usually change from green to brown or straw color.

In grasses, seed maturity after flowering goes through the following stages:

(1) Milk stage: when squeezing a seed between the thumb and forefinger, a milky substance is secreted. Seed has no viability.

(2) Soft-dough stage: excretion of dough when squeezed. Seed has low germination and viability.

(3) Hard-dough stage: no excretion of dough when squeezed. Seed collection should start at the transition of soft-dough to hard-dough. At this stage, the chance of obtaining plump, fully matured seed can be increased by not stripping the seed from the plant. Instead, cutting seed heads from the plant will allow the maturity process to continue as the collected material dries.

(4) Mature: seed is usually too hard to bite. Maturity and seed shatter may occur at the same time.

(g) If monitoring or early collections indicate that seed soundness and crop quality are degraded because of uncontrollable biological problems such as poor pollination or low seed set, then the Contractor shall provide a representative sample to the COR for determination as to whether the collection should continue.

(h) Seed may be harvested by stripping or knocking it off the stem, or by clipping the stem just below the inflorescence.

For species that dehisce explosively, the entire inflorescence may be cut prior to maturity or and allowed to dry in mesh or paper bags, or under netting. Net bags placed over the inflorescence to collect the seed as it dehisces may be necessary.

(i) Seed will be collected in approximately equal quantities amongst the approved collection sites. To ensure adequate genetic representation, collect from many widely spaced or unrelated parent plants per site (over 50 is optimal).

Collection of early seed and later seed also helps represent genetic diversity.

(j) Seed or seed-bearing fruits shall not be collected if they touch the ground.

(k) Seed shall be collected and stored in such a way as to ensure its viability. Special handling is required for fleshy fruits see section 3.3 below. should be refrigerated until the full collection is made. Then shipped to extractor while still fresh. Do not freeze seed. Use resealable plastic bags and do not fill more than ½ full. Do not allow collections to overheat, and do not leave them in a vehicle in full sun. Exposure to sustained high temperatures can badly damage the seed collections. As soon as collection is done shipping to Bend Seed Extractory will need to be made with the COR.

Standard:

Acceptable Quality Level (AQL):

3.4 Cleaning, packaging, labeling, storage and delivery standards

Collected seed shall remain in separate bags delineating each site, and PSZ by species. No bulking, aggregation, or combination shall occur without consultation with the COR. Prior to delivery to the COR, seeds shall be hand-screened, stripped, or otherwise cleaned to remove excess chaff, stems, leaves, trash, dirt, and other impurities, including seeds of other non-target species (See Table 3.3)

Table 3.4 Acceptable cleaning methods for “rough cleaned” seed by plant type

Common Name Seed Cleaning Methods grasses Screened or stripped seed is acceptable forbs Seed heads and small amounts of chaff acceptable.

Shrubs Seed heads and small amounts of chaff acceptable.

(a) Seeds of non-fleshy species (e.g., grasses and forbs) shall be dried down to reduce moisture content prior to hand-cleaning.

(b) Seeds shall be in a separate bag(s) by item, location and PSZ. Each seed bag itself shall be labeled with the species, item code, and the year of collection (e.g., DECE-1-2020). If multiple packages are required for a species, they shall all have this same label. Only permanent marking pens shall be used.

(c) Dried and cleaned grass and forb seed shall be packaged in paper bags.

(d) Fruits should be refrigerated and fresh until the full collection is made and shipped to the extractor in Bend. Do not freeze fruits or seeds. Use Ziplock type bags and do not fill more than ½ full. Do not allow collections to overheat, and do not leave them in a vehicle in the sun. Exposure to sustained high temperatures can badly damage the seed collections. As soon as collection is done shipping to the Bend Seed Extractory will need to be made in coordination with the COR.

(e) Each seed package shall have two of the Bag Identification Forms (Attachment 3). Electronic copies of this form will be provided. Remaining information may be documented by hand or electronically, whichever is most convenient. One completed Bag Identification Form will be placed inside the bag and another one shall be stapled to the outside of the bag. If multiple bags are required, each one will have 2 copies of this form. Each bag will then be labeled by a bag number at the top of the attached forms and on the bag itself as follows (plant code bag # ”of” total bags for that species).

I.e. first bag labeled “BRCA-1-2025_ 1of 5”, second bag labeled “BRCA-1-2025_bag 2 of 5”. Only permanent marking pens shall be used.

(f) The Contractor shall weigh each bulked seedlot and record this information on the Seed Collection Summary Form below (Attachment 7). Any Individual Site Seed Collection Forms (Attachment 3) that have been filled in manually shall be stapled to the Seed Collection Summary Table.

Noxious Weed Control Classification Definitions

Noxious weeds, for the purpose of this system, shall be listed as either A or B, and may also be designated as T, which are priority targets for control, as directed by the Oregon State Weed Board.

• A Listed Weed:

A weed of known economic importance which occurs in the state in small enough infestations to make eradication or containment possible; or is not known to occur, but its presence in neighboring states make future occurrence in Oregon seem imminent (Table I).

Recommended action: Infestations are subject to eradication or intensive control when and where found.

• B Listed Weed:

A weed of economic importance which is regionally abundant, but which may have limited distribution in some counties (Table II).

Recommended action: Limited to intensive control at the state, county or regional level as determined on a site specific, case-by-case basis.

Where implementation of a fully integrated statewide management plan is not feasible, biological control (when available) shall be the primary control method.

• T Designated Weed (T):

A designated group of weed species that are selected and will be the focus for prevention and control by the Noxious Weed Control Program. Action against these weeds will receive priority. T designated noxious weeds are determined by the Oregon State Weed Board and directs ODA to develop and implement a statewide management plan. T designated noxious weeds are species selected from either the A or B list.
