Transcript: The NPS has collected Monitoring data, 2012-2015 Egg Harvest Background Walking on Eggshells: Monitoring provides snapshots in time, but does not incorporate dynamism or interactions between ecological variables. Monitoring -Can- AM be used in designated Wilderness? Solutions 1) develop innovative experimentation and monitoring methods to reduce uncertainty -Vegetation -Predation 2) Commit funding resources to long term monitoring and research. (-No future monitoring is planned.) Problem Statement & Research Questions NPS Management Problem: NPS must protect Natural -and- Cultural resources. Harvest must "not impair the biological sustainability of gull population" inside GLBA. Gull colonies are dynamic Nesting habitat Predation Food Availability Gull eggs: key Huna Tlingit cultural food Subsistence ended by NPS in 1960's Fractious NPS/Native relationship Effort to legalize harvest since 1997 TEK and Gull Biological studies (1999-2002) LEIS (2010) Legislation signed by president July 2014. Ongoing: REGULATION PROMULGATION! Managing a Native Gull Egg Harvest in Glacier Bay National Park. LEIS (2010) "Monitoring of egg harvest activities, gull productivity, gull egg predation, and marine mammal disturbance and subsequent adaptive management would help ensure that the park’s purposes and values would be protected." Question: What might "adaptive management" of the Huna Egg Harvest look like under conditions of ecological dynamism, high uncertainty, and low controllability? "AM-Lite" "Adaptive Management" is nowhere defined. -Boat based "Chick-counts" are extremely error prone, even worthless. -Does not differentiate between breeding adults and non-breeding adults. -Egg counts confounded by predation, -No link between number of eggs at a given time and fledging rate/juvenile survival.

Food Availability Intertidal/Forage fish On the positive side, an "experimental" egg harvest was conducted in 2015 HIA/NPA relations are improving. NPS Monitoring has methodological issues Whats the ultimate question for management? This monitoring includes: -Colony distribution -Onset of laying -#'s of nests/eggs -Island circum. counts -Other species present How do harvest decisions impact gull population? (We dont know!) There is no link between actions and outcomes! Thanks for Your Time! How will the NPS "Manage" the Egg Harvest? Adaptive Management in name only. --Still "Ad-hoc" decision-making Now, What should the park monitor? Population Dynamics Recruitment, Im/Emigration, mortality,

Transcript: On Nature, Gender, Race, Religion and "Self-Reliance" A critique of cosmology within the work of white American men writers that impacts our understandings and experiences of nature within National Parks Christian Scientists and the Scientific Revolution (17th c) Scientific Revolution deepens the constructed link between Christian understandings of nature, womanhood, and morality. Dualism is a problem. "It treats nature as a female to be tortured through mechanical inventions" - Merchant on FB's Christian philosophy of science Ideas still present in our modern experiences of nature What's the point? - The assumptions that color our understandings of race, gender, Christianity, and nature are neither natural nor universal. - In fact, they are often actively harmful to human beings as well as the non-human world. - All of these modern ideas were constructed in tandem with each other over centuries of colonization, and when we understand how they were created we can also deconstruct them. The implications of these ideas about women and nature are not accidental; they allow white men of Christian heritage to consciously and unconsciously understand themselves as the dominators of all other living beings, including non-white people and women. Still impacts the National Park Service today (lawsuits, environmental policy). Zion National Park and the "sublime" Early European settlers ideas about wilderness in the 'New World' are first constructed through Christian discourse, but the concept changes over centuries of colonization in America "Wilderness is quite profoundly a human creation" - William Cronon. Without a population that feels separate from nature, wilderness does not exist. Industrialization, secularization, and westward expansion all contribute to this changing definition of wilderness. “Gender, the bundle of habits and expectations and behaviors that organizes people and things according to ideas about the consequences of sexed bodies, is a crucial, deep, and far-reaching medium through which we encounter nature.” - Virginia Scharff, Seeing Nature Through Gender Colonization and women, wilderness, demons (17th c) Wilderness as chaotic, unholy, sexualized -> the only place where a man can truly commune with God Early European settlers like the Puritans viewed the world outside of their settlements as the chaotic, unholy abode of witches, devils, and demons. Gendered and racialized myths are rampant in these early constructions of nature; they never fully go away. Excerpted from Carolyn Merchant's The Death of Nature How does this change happen? - Through centuries of colonization, indigenous displacement, renegotiations of the Christian experience, and the heavy intellectual lifting of white men writers like Emerson, Thoreau, and John Muir - Muir actively and successfuly advocates for the institutionalized preservation of "public land" - Emerson's essay "Self-Reliance" in particular argues for that a man can only be a real Christian when living "alone" in "nature" (ironic) Logo
