est, appears in the Biological Assessment. Although the Forest Service states, in the FEIS, that “[ajnnual monitoring for presence, abundance, and nesting [of the Southwestern willow flycatcher] are [sic] conducted by the Forest Service and the Utah Division of Wildlife Resources,” (2 AR Doc. 485 at III — 64), we were unable to locate quantitative data from either the Forest Service or the Utah Division of Wildlife Resources in the record.
Despite the absence of actual data in the record, the effects analysis in the FEIS concludes that the current management of the Monroe Project area could harm the southwestern willow flycatcher’s habitat. While annual monitoring of the southwestern willow flycatcher’s presence, abundance, and nesting is sufficient to meet the Forest Service’s obligations under the Fishlake Forest Plan and § 219.19, because we find no such data in the record, we are unable to conclude that the Forest Service fulfilled its obligations under § 219.19 in monitoring this MIS.

Our review of the record regarding sage grouse and sage nesters leads to a similar conclusion. In its brief, the Forest Service acknowledges that “[s]age grouse are potentially present,” “unconfirmed sightings” of sage grouse have been made, and habitat suitable for the sage grouse is present in the Monroe Project area. (Appellees’ Br. at 23.) Because, however, the Monroe Project is anticipated to “alter only two or three percent of the sagebrush habitat,” the Forest Service concluded that the Monroe Project “will not threaten the viability of the sage nesters.” (Appellees’ Br. at 48-49.)
As to its monitoring obligations, the Forest Service directs our attention to the Burnt Flat Analysis, which included an analysis of a survey of the sage nesters (the guild to which the sage grouse belong). The Burnt Flat Analysis, conducted in 1994, surveyed thirty-seven different species of birds, yet reviewing the Burnt Flat Analysis included in the record, we discovered no quantitative data regarding either the sage grouse, or the sage nester guild specifically.
As a final matter, notably, the district court determined that because there “have been no known sightings of ... Sage Nes-ters on Monroe Mountain,” the Forest Service could not collect hard population data, and relying in part on Dombeck, the court refused to interpret the language of the NFMA to require the impossible. (Dist. Ct. Order at 19.) Although we agree with the district court that where impossible, the Forest Service is not required by the applicable statutes and regulations to collect population data, we part with the district court’s further reasoning that when faced with “difficult-to-count” species, the Forest Service may reasonably disregard its obligation to obtain quantitative data and choose to allocate its resources elsewhere. (Id.) This extension of the reasoning of Dombeck is troublesome in this context, where the Fishlake Forest Plan specifically states that the MIS selected for the plan were chosen, in part, due to “[r]elative ease of monitoring.” (2 AR Doc. 544a at 11-27.) Moreover, because MIS, if they are to serve their purpose as a class representative in the Fishlake Forest Plan, should generally not be difficult-to-count species, and because the Forest Service did not argue to us that the sage grouse and sage nesters are reclusive and hard to track, we decline to follow the reasoning in Inland Empire, 88 F.3d 754, 763 n. 12 (finding that the MIS at issue was a “reclusive species” and there was no “technically reliable and cost-effective method of counting individual members of the species”).
Of course, not all MIS designated in the Fishlake Forest Plan are necessarily
