Human resources available to facilitate the implementation of the conservation plan include government<br />

agencies that provide technical support and/or funding for conservation-related activities (Appendix C) and<br />

various community organizations focused on environmental issues (chapter 7, section 7.5). Key leadership<br />

for this endeavor will likely come from agencies such as the Pennsylvania Department of <strong>Conservation</strong> and<br />

Natural Resources (PADCNR), the Pennsylvania Department of Environmental Protection (PADEP), the <strong>Erie</strong><br />

County <strong>Plan</strong>ning Department, the <strong>Erie</strong> County <strong>Conservation</strong> District (ECCD), Pennsylvania Sea Grant, and<br />

the Pennsylvania Lake <strong>Erie</strong> <strong>Watershed</strong> Association (PLEWA [http://www.eriewatershed.org/]).<br />

Threats to Aquatic and Natural Resources<br />

The most serious threats to maintaining high-quality aquatic and associated natural resources in the<br />

Pennsylvania Lake <strong>Erie</strong> watershed are non-point source pollution (NPSP), urban sprawl, and climate change.<br />

Non-point source pollution began with historic changes in regional hydrology accompanying deforestation,<br />

draining and filling wetlands, and the alteration/degradation of streams associated with the growth of local<br />

industry, transportation systems, and urban centers (chapter 4). Non-point source pollution affects important<br />

non-stream aquatic resources in the watershed, namely Lake <strong>Erie</strong> (chapter 5, section 5.1) and Presque Isle<br />

Bay (chapter 5, section 5.3).<br />

Chapter 5 (especially section 5.10.3) provides a detailed analysis of sources and effects of NPSP on the<br />

watershed's streams. Major concerns include: (1) substrate degradation due to development activities; (2)<br />

sediment, nutrients, metals, and hydrocarbons delivered to streams during storm events; (3) mercury and<br />

nitrate deposition from atmospheric sources; (4) pesticides from agricultural and urban areas; (5) unregulated<br />

organic contaminants known as PPCPs (pharmaceutical and personal care products) and EDCs (endocrine<br />

disrupting compounds) that enter our water through sewage treatment plants; and (6) bacterial (Escherichia<br />

coli) contamination of streams and the lake from both point and non-point sources in the watershed (section<br />

5.10.5).<br />

Non-point source pollution affects most of the 75 miles of "non-attainment" stream segments in the<br />

Pennsylvania Lake <strong>Erie</strong> watershed (chapter 5, section 5.10.4), with small- and medium-sized streams in the<br />

built-up portions of the lake plain being most affected. Our watershed's small headwaters streams serve an<br />

important protective role as buffers against NPSP and adverse effects of climate change on groundwater<br />

supplies and cold water fisheries (chapter 10, section 10.3); however, headwaters are not vigorously protected<br />

by current regulations affecting development in our watershed.<br />

Urban sprawl is the second major threat to maintaining the quality of our watershed's aquatic and natural<br />

resources. The demand to continue the expansion of infrastructure to distribute surface withdrawn from Lake<br />

<strong>Erie</strong> to locations beyond the City of <strong>Erie</strong> (chapter 5, section 5.11) is expected to increase in the future (chapter<br />

8). Increasing impervious surfaces relative to undisturbed natural vegetation results in increased runoff and<br />

siltation, which in turn degrades stream habitats for aquatic animals (chapter 5, section 5.10.4) and disrupts<br />

important habitat connections needed by amphibians in our watershed (chapter 6, section 6.1.3). Urban sprawl<br />

also harms people in our watershed, as it results in a redistribution of economic opportunities to the suburbs.<br />

This leads to increased poverty in urban and rural areas as well as huge hidden costs to the community, as<br />

shown by recent studies focusing on sprawl and poverty in <strong>Erie</strong> and other similar communities (chapter 8,<br />

section 8.2). Fortunately, the top-level leadership in Pennsylvania, namely Governor Rendell's Economic<br />

Development Cabinet, has set forth a policy and guidelines for sustainable development (chapter 8, section<br />

8.3), which—if followed—will help to decrease the harmful effects of urban sprawl.<br />

The third major threat to the long-term integrity of our watershed's resources is ongoing climate change,<br />

mentioned in earlier sections of this summary. It may be impossible to prove with certainty whether the<br />

current climate change situation is due primarily to our modern society's excessive greenhouse gas emissions<br />

or the culmination of a natural change event that commenced more than 150 years ago (chapter 4). In either<br />

case, there are well-documented indications that the world is changing, and analyses by some of the country's<br />

best scientists provide reasonable forecasts of how natural resources in our region are likely to be affected<br />

by a warmer climate (chapter 6, sections 6.1.8 and 6.3.4). The most serious consequences include a challenge<br />

to our economically important cold water fisheries and threats to water supplies due to increased evaporation<br />

and reduced groundwater recharge. Prudent management of our water resources, careful planning of future<br />
