Dear Ms. Morgan:
This responds to your biological assessment (BA) requesting informal consultation for the effects of the Sulphur Forest Restoration Project on the Sandia Ranger District, Cibola National Forest. As documented in your BA, which is hereby incorporated by reference, we find that your proposed action wi l l have insignificant and discountable effects to the Mexican spotted owl (Strix occidentalis lucidd) (MSO). Therefore, the Service concurs with your determination of "may affect, is not likely to adversely affect" the MSO for the following reasons: 1) surveys conducted according to the currently accepted protocol indicate that potential and/or suitable habitat within the proposed action area and within one half-mile of the action area are currently unoccupied; 2) it is not likely that MSO currently use the action area for foraging, and 3) it is unlikely that MSO wil l disperse into the action area during implementation of the proposed action.
This concludes section 7 consultation regarding the proposed action. I f monitoring or other information results in modification or the inability to complete all aspects of the proposed action, consultation should be reinitiated. Please contact the Service if: 1) future surveys detect listed, proposed or candidate species in habitats where they have not been previously observed; 2) the proposed action changes or new information reveals effects of the proposal to listed species that have not been considered in this analysis; or 3) a new species is listed or critical habitat designated that may be affected by the action.
Thank you for your concern for endangered species and New Mexico's wildlife habitats. I f you have any questions, please contact Eric Hein of my staff at the letterhead address or at (505) 761-4735.

Biological Assessment
Sulphur Forest Restoration Project Sandia Ranger District
Cibola National Forest
USDA Forest Service Southwestern Region
Bernalillo County, New Mexico
A. INTRODUCTION: The Cibola National Forest is proposing to implement the Sulphur Forest Health
Restoration Project on the Sandia Ranger District. The purpose of this Forest Restoration
Project is to move the existing conditions in the 1677 acres project area towards the
desired conditions outlined in the Cibola National Forest (CNF) Land and Resource
Management Plan (LRMP) of 1985 as amended in 1996 for Mexican spotted owl and
Northern goshawk. High tree densities in the area have an ongoing potential for insect and
disease outbreaks and increases in potential for uncharacteristic wildfire. On a majority of the
project area fire no longer plays its natural role in maintaining ecosystem structure and function.
The objectives of this landscape restoration project are to conduct treatments to restore
forest health for resiliency to drought, insect and disease, and uncharacteristic wildfire.
Treatments that promote an uneven-aged forest structure and mimic natural disturbance
patterns will also increase wildlife and vegetation diversity and improve scenic quality.
Improved forest health includes an uneven aged stand structure for vegetation, properly
functioning riparian areas in satisfactory conditions, a reduction of fuel ladders
(vegetation that allows fire to climb into the tree canopy) to limit the severity of future
fire events, enhanced watershed functions, and enhanced scenic quality e.g. enhancing
views and spatial distribution of trees. Overall, the objectives of thinning will be for
wildlife habitat improvements, fuels reduction, and visual resource enhancement, with
secondary benefits of providing firewood.
Project Location: The Sulphur Forest Restoration Project area is located in the Wildland
Urban Interface along the eastern boundary of the Sandia Ranger District (SRD) in
Bernalillo County. It begins directly south of New Mexico State Highway 536 and
extends south for approximately 3 miles to the CNF Boundary in portions of Township
11 North, Range 5 East, sections 14, 15, 22, 23, 26 and 27 New Mexico Principal
Meridian.
The project area is within Management Area 2, as defined by the CNF LRMP,
“Management emphasis is on providing opportunities for a variety of year round
recreational experiences consistent with guidelines established for maintaining viable
wildlife populations and ecosystem health. Wildlife diversity and population viability
will be maintained or improved through habitat management using such tools as
prescribed fire, timber or firewood collection, or structural improvements to attain
2
identified goals and objectives for the management area. Map 1 shows the location of the
Sulphur project area.

B. DESCRIPTION OF THE EXISTING CONDITION Vegetation growth within the project area has been vigorous over the last several decades
and has resulted in a dense overstory (i.e. high crown density). This dense overstory,
combined with the exclusion of wildfire for over a century and dry climate conditions,
has resulted in fuel conditions that favor high intensity wildfire with unpredictable
behavior. Portions of the project area have been previously treated to reduce fuel loading
and protect nearby property in the event of an uncharacteristic wildfire (1995 Cienega
Picnic Area Fuelbreak and 2002 Armijo Fuelbreak). However, these projects were not
maintained and their effectiveness has been compromised due to vigorous spouting of
Gamble oak and juniper as well as needlecast. All of the fuelbreaks are in need of
maintenance.
Landscapes in the proposed project area are currently managed for either the northern
Goshawk or the Mexican spotted owl, as described in the LRMP. Mexican Spotted Owl
(MSO) habitat in the proposed project area include Recovery Habitat (formerly known as
Restricted Habitat) consisting of mixed conifer and minor amounts of riparian habitat.
There are approximately 681 acres of MSO Recovery habitat scattered in patches
throughout the entire project area.
Habitat in the project area consists of Mixed Conifer (681 acres), Pinyon and Juniper
Woodland (544 acres), and Ponderosa Pine (445 acres) as well as riparian areas (7 acres).
Dry Mixed Conifer Habitat Existing Condition: The existing condition of mixed conifer
in the project area, based on stand exam data, is as follows: Density of trees greater than
5” Diameter Breast Height (DBH) ranges from 180-640 trees per acre. In addition stands
have an average of 3,261 trees less than 5” DBH per acre. Overall, canopy closure is
60%+. These areas are primarily even-aged lacking structural diversity. Mixed conifer
forest types in the project area are also experiencing competition which is causing
mortality, declining health, and increased susceptibility to insect and disease activity, as
well as wildfire. Natural canopy gap processes are occurring especially where white fir
has died as a result of broom rust thus producing horizontal variation in stand structure.
As part of the existing condition analysis the CNF conducted a review of stand data at
three scales. The results are presented in the table 1.

The desired condition of the Mixed Conifer forest type is consistent with requirements set
forth for Management Area 2 in the LRMP, with twenty percent (20%) maintained as
threshold conditions for Mexican Spotted Owl restricted habitat. Densities within the
mixed conifer forest type will be approximately 90-115 trees per acre. Approximately
10% of this forest type will exist as temporary openings for recruitment of the VSS 1 and
2 structural stages. Canopy cover within this forest type will remain intact except for the
temporary openings. 136 acres (20%) will be maintained for MSO threshold conditions.
Riparian Habitat Existing Condition: Riparian areas are located near Canoncito Spring,
Armijo Spring and in the developed picnic areas at Doc Long, Sulphur and Cienega.
There is an overlap of recreation trails and picnic areas with riparian habitat causing
degradation of habitat and displacement of wildlife. Some riparian areas have been
degraded due to non-native plant species invasion and conifer encroachment, as well as
shading and crowding out of riparian vegetation, as a result of past management practices
such as the exclusion of fire. In these areas, there is little shrub or herbaceous understory
and bank stability has been reduced allowing accelerated channel degradation and
increases in sediment.
The desired condition for the riparian habitat type is as follows: Maintain or provide 60
percent of woody plant composition in three or more riparian species or as appropriate for
the site. Plant Structure consists of three age classes of riparian woody plants with at
least 10 percent of the woody plant cover in the sprout seedling and sapling stages and 10
percent in the mature and over-mature. Crown Cover for both trees and shrubs should be
at least 60 percent of natural levels. The desired condition of Mexican Spotted Owl (MSO) habitat is consistent with the CNF
LRMP, to provide three levels of habitat management – protected, restricted, and other
forest and woodland types to achieve a diversity of habitat conditions across the
landscape. The project area includes MSO Restricted Habitat. There are no PACs or
Protected habitat in the analysis area based on surveys conducted to MSO Survey
Protocol. In Restricted Habitat forest direction is to manage to ensure a sustained level
of owl nest/roost habitat well distributed across the landscape and create replacement owl
nest/roost habitat where appropriate while providing a diversity of stand conditions
across the landscape to ensure habitat for a diversity of prey species. A minimal
percentage (10%) of restricted habitat should be managed to have nest/roost
characteristics. The western portion of the project area has been designated to meet the
MSO threshold conditions and will not be treated. Over time, multiple treatments are
needed to create conditions for safely reintroducing fire into the National Forest. This is
due to the nearly total exclusion of fire for a century or more. A return to the more
natural fire regime will reduce the potential for high intensity stand-replacement fire
inside or outside of the Forest. In turn, this will allow continued protection of the habitat
of any threatened, endangered, and sensitive wildlife species in the Forest.

C. DESCRIPTION OF THE PREFERRED ALTERNATIVE
Following is a Summary of Specific Vegetation Treatments in MSO habitat: Mixed Conifer: Habitat will be managed to ensure a sustained level of owl nest/roost
habitat well distributed across the landscape. Replacement nest/roost habitat will be
created where appropriate while providing a diversity of stand conditions across the
landscape to ensure habitat for a diversity of prey species.
Treatment will promote an uneven-aged forest structure with native species diversity and
natural variation by retaining all age classes and sizes. All large trees over 16” DBH or
DRC will be retained. Treatments will be a “free thinning” of up to 15.9” DBH or DRC
by retaining trees to a residual of 90-115 TPA, (Trees Per Acre) including up to 10% of
trees with dead tops, decadence, and/or irregular crowns to provide habitat for a variety
of prey species. All large oaks and native deciduous hardwoods (10” DRC and greater)
will be retained and natural regeneration will be promoted by removing competing
conifers. Existing patches of snags will not be treated unless determined to be hazard
trees. Twenty percent (136 acres) of the mixed conifer in the project area will not be
treated and will be maintained for threshold conditions for Mexican Spotted Owl
nest/roost replacement habitat Natural disturbance patterns will be mimicked on up to
10% of 149 acres to provide spatial heterogeneity and horizontal variation by creating
temporary openings that range from 1/10th of an acre to ¼ of an acre in size. Key habitat
components (such as an average at least 2 snags and 10-15 tons of downed woody debris
per acre) will be retained. Skid trails, landings and other intensely disturbed areas will be
seeded with native grass/forb/shrub seed mix.
Riparian: Designated native conifers and nonnative (invasive) species will be thinned in
order to move the vegetation in this area towards native hardwoods and riparian
vegetation species. Treatments will create and/or enhance riparian features such as
downed logs and bank stability to provide for wildlife habitat and a functioning riparian
area. Large, downed woody materials (12” diameter midpoint and greater) and snags
within riparian areas will be retained. No skid trails or landings will be located in riparian
areas. Treatment in riparian acres will emphasize maintenance and restoration of healthy
riparian ecosystems through conformance with forest plan riparian standards and
guidelines. Damage to riparian vegetation, stream banks, and channels will be prevented.
In addition, the Canoncito Trail which is poorly located and significantly contributing to
sediment in the drainage as well as damaging the limestone terraces and riparian habitat
will be relocated to will improve riparian habitat. Table 2 is a summary of treatments in
MSO habitat.

D. SPECIES IDENTIFICATION
The following Endangered and Threatened species are considered as having the potential to occur within the analysis areas. U.S. Fish and Wildlife Service species lists were consulted for identification of species. County lists referred to included Bernalillo County. The following species were identified with the Information,
Planning, and Conservation (IPaC) decision support system. Table 4. Federally-listed species potentially occurring in Bernalillo County.

the other species will be considered further in this Biological Assessment because their
habitat does not occur in the project area or the project area is not within their known
range.
E. SPECIES EVALUATION
1. Mexican spotted owl (Strix occidentalis lucida) Threatened, endangered, or proposed wildlife species which may occur or have potential
habitat in the project area include the Mexican spotted owl (MSO). No known Protected
Activity Centers (PACs) or Designated Critical Habitat occur within the project
boundary; potential Recovery Habitat exists in the 681 acres of mixed conifer forest and
the 7 acres of riparian habitat. The analysis of effects to MSO is being considered
under the 1995 MSO recovery plan rather than the 2012 MSO Recovery Plan
Revision since the project was scoped with the pubic prior to the release of the 2012
Recovery Plan.
a. Data Sources, including surveys conducted: The Sulphur project area was surveyed to protocol in 2008 and 2009 but no owls were located. Previously, all suitable habitats in the Sandia and Manzanita Mountains were surveyed to protocol in 1990-92 and again in 2004-2006. The analysis area is not within designated Critical
9
Habitat or Protected Habitat for the MSO, and is within the Basin and Range East Recovery Unit. Only one MSO territory was known on the Sandias, within the Sandia Wilderness Area on the northwest side of the District, until May, 2014 when a single male was discovered in Tecolote Canyon. This territory is located outside of the project area, but the PAC boundary has not been delineated. Two years of surveys on the mixed conifer portion of the adjacent Hondo project area did not find the owl to be present either. Those surveys were also conducted to protocol in 2008 and 2009. Further surveys are being conducted in support of the La Madera Landscape level project in the Sandias to the north of the project area. This is where the single male was discovered in May, 2014. b. Affected Habitat Description: The project area is in the Basin and Range East Recovery Unit (now known as Ecological Management Unit). There is no Protected Habitat in the project area. Restricted Habitat in the project area is comprised of mixed conifer and riparian vegetation. In the mixed conifer forest, much of the habitat
in the project area is in canyon bottoms and north facing slopes. Old growth trees with
associated downed logs and woody debris are present and will be managed as important
habitat features. Springs, seeps, and other water sources are located in the project area
and are more common in the mixed conifer habitat type, as are rock outcrops and snags.
Management of habitat for the Mexican spotted owl is the primary consideration for
management of this habitat type.
c. Analysis of Effects: Alternative B: In general the Preferred Alternative (Alternative B)
provides reduced potential of stand replacing wildfire since fuels would be reduced
throughout the area. An uneven-aged forest structure with native species diversity and
natural variation would be created by retaining all age classes and sizes. All large trees
over 16” DBH or DRC will be retained.
The proposed action incorporates designs to lessen effects to Mexican spotted owl.
Implementation of Alternative B would provide essential habitat components such as
snags, downed logs, residual basal area, and canopy cover necessary for potential
occupancy of the Mexican spotted owl and Northern goshawk.

There will be a continuation of fuels
build-up and small diameter (ladder)
trees, leading to a potential crown
fire if wildfire occurs in the area.
Important habitat features such as
snags, and large down logs could be
burned. Riparian habitat would not
be improvedthrough the relocation
of the Canoncito Trail and removal
This alternative would reduce ladder
fuels; maintain snags, downed logs and
residual basal area for potential MSO
occupancy on 681 acres of mixed
conifer habitat. Tree cutting would
occur in unoccupied mixed conifer
habitat, with methods and results being
consistent with the Forest Plan. Trail
reroutes are generally located outside
10
The threat of catastrophic wildfire is one of the threats identified in the Mexican Spotted Owl Recovery Plan (1995). Prescribed burning stands and keeping fire “on the ground” by reducing ladder fuels will help protect not only neighboring land jurisdictions, but may aid in reducing the spread of fire into higher elevation mixed conifer in the Sandia and Manzano Wilderness areas (higher quality MSO habitat). Snags and dead trees will be retained (all species of trees); and large woody debris will be retained. The CNF LRMP Plan Amendment regarding Restricted Habitat also has basal area requirements for post-treatment retention in mixed conifer. The following table (with the Basin-Range East Recovery Unit highlighted in bold type) notes basal area standards Table 6.

The expected improvement in understory plant species composition would allow for greater prey species diversity of small mammals such as vole and deer mice species. No livestock grazing occurs in the Sandia Mountains, so understory recovery will not be impacted by cattle;. Since marginal nest/roost habitat exists, project actions may increase the value of the area as a foraging site for MSO. d. Determination of Effect/Recommended Mitigation:

G. OTHER SPECIES CONSIDERED BUT NOT EVALUATED The U.S. Fish and Wildlife Service list of threatened, endangered, and proposed species
which may occur in Bernalillo County was reviewed to determine potential wildlife and
plant species which may occur in the analysis area. The following Threatened, Endangered, or Candidate species in Bernalillo and Bernalillo Counties were considered but not evaluated due to the absence of suitable or potential habitat in the analysis area. There is no Critical Habitat for listed species in the analysis area.

H. CONSULTATION COMPLETED TO DATE There has been no formal consultation with the U.S. Fish and Wildlife Service to date. A complete list of all federally-listed and candidate species potentially occurring in Bernalillo County was compiled. All species on this list with potential to occur in habitat where the proposed action will occur were evaluated and discussed. Other species were not discussed because they occupy habitat types not applicable to the project area. I.
