BIOLOGICAL IMPACTS ASSESSMENT <br />Very little open space remains within the City of Santa Ana, after the vast majority of <br />land in the City was converted to residential, commercial and industrial uses. The little <br />open space that remains is therefore of critical habitat value to resident and migratory <br />wildlife. The site composes a diminishing patch of open space within an expanse of <br />anthropogenic land uses, forcing more birds to use the site as stopover and staging <br />habitat during migration, dispersal, and home range patrol (Warnock 201o, Taylor et al. <br />2011, Runge et al. 2014). Should the project go forward, the lost stopover value of the <br />site would expose birds moving through the area to even greater energetic challenges <br />than they already experience. Many of these birds would be less capable of negotiating <br />collision hazards. <br />That many birds fly through the aerohabitat of the greater Los Angeles megacity has <br />long been known. The project site is on the Pacific Flyway and near the coast, where <br />millions of birds annually fly through on migration. Just this past spring, on 22 April <br />2020, the Cornell Lab of Ornithology's Birdcast project documented 66,044 birds/km <br />flying nocturnally within detection range of radar at the KVTX Los Angeles station <br />(https: //birdeast.info/scientific-discussion/migration-update-morning-flight-madness- <br />in-southern-california-22-april-2o20/). Because of this migration and for other <br />reasons, the Los Angeles Basin is a biodiversity hot spot. Often unseen by human eyes, <br />migrating birds fly day and night, often stopping over in whatever open space is <br />available and in trees. Each time migrants take off again for the next leg of their <br />migration, they will do what they must to conserve energy. Too often, these birds will <br />attempt to fly the shortest distance along falsely perceived pathways through the <br />structural glass panels of buildings. And too often, they will attempt to fly to the next <br />tree, or to the image of the tree that is reflected on the glass panel of a building. This is <br />the type of impact my comment letter addresses. <br />Since the 2007 EIR and 2o18 SEIR, ornithologists learned that North American bird <br />abundance declined 29% over the last 48 years (Rosenberg et al. 2019). Although the <br />ecological and economic consequences of this decline have yet to be understood, they <br />are likely to be severe. In response to this new circumstance — whether directly or <br />indirectly, Governor Newsome signed AB 454 into law on 27 September 2019. This new <br />law amended California Fish and Game Code section 3513 to further protect birds <br />addressed by the federal Migratory Bird Treaty Act. This new law carries particular <br />significance for the impacts of window collisions that the proposed project would have <br />on birds, as I will discuss shortly. <br />Not only do all native migratory birds now have the additional protection of California's <br />Migratory Bird Treaty Act, but at least 44 special -status species of bird are known to the <br />project area (Table 1). With the release of a study just this year, we also know that 21 of <br />these special -status species have been documented as window collision fatalities and are <br />therefore susceptible to new structural glass installations (Basilio et al. 2020: <br />Supplemental Material). Many more species newly protected by AB 454 have also been <br />documented as window collision victims (Basilio et al. 2020). <br />2 <br />
