OVERVIEW OF THIS TALK

WHO IS INVOLVED

EPA’s REQUEST FOR APPLICATIONS

RESPONSES FROM

CSU - Major Participants

Oregon State University

POTENTIAL FOR COOPERATION HERE

WHAT IS EMAP {MINIMZE THIS NOW}

# 2

WHO IS INVOLVED?

Jay Breidt

Richard Davis

Jennifer Hoeting

Hari Iyer

Scott Urquhart

Dave Theobald - Natural Resources Ecology Lab

Robin Reich - Forest Science

Jim Loftis - Bioresources Engineering

Collaborators at OSU, SCCWRP, WQTI

# 3

EPA’s REQUEST FOR APPLICATIONS (RFA)

CONTENT REQUIREMENTS

RESEARCH IN STATISTICS

MANY OF US WOULD CALL THE REQUESTED “RESEARCH” ADAPTATION or DEVELOPMENT

TRAINING OF “FUTURE GENERATIONS” OF ENVIRONMENTAL STATISTICIANS

OUTREACH TO THE STATES and TRIBES

ADMINISTRATIVE REQUIREMENTS

# 4

EPA’s REQUEST FOR APPLICATIONS (RFA) - continued

MAJOR ADMINISTRATIVE REQUIREMENT

“… EACH OF THE TWO PROGRRAMS ESTABLISHED WILL INVOLVE COLLABORATIVE RESEARCH AT MULTIPLE, GEOGRAPHICALLY DIVERSE SITES.”

CLOSE COOPERATION BETWEEN TWO PROGRAMS

SPECIFICALLY TO AVOID DUPLICATION OF EFFORT

===> JOINT ANNUAL MEETING ++

# 5

EPA’s REQUEST FOR APPLICATIONS (RFA) - continued III

FUNDING LEVEL: $750K/YEAR/PROGRAM

THE TWO PROGRAMS:

DESIGN-BASED/MODEL ASSISTED SURVEY METHODOLOGY - @ OSU

SPATIAL AND TEMPORTAL MODELING, INCORPORATING HIERARCHICAL SURVEY DESIGN, DATA ANALYSIS, MODELING - @ CSU

CHECK ON THE RFA @

CSU PROPOSAL - CONTENT

1. COMBINING ENVIRONMENTAL DATA

2. LOCAL INFERENCE

3. AQUATIC INDICATORS

4. OUTREACH

5. ADMINISTRATION/COORDINATION

# 8

CSU PROPOSAL - APPROACH

TAKE EXISTING SETS OF

PROBABILITY &

NON-PROBABILITY DATA

START WORKING WITH THE DATA WITH A PERSPECTIVE OF DRAWING INFERENCES

IDENTIFY ISSUES WE DON’T KNOW HOW TO HANDLE

HAVE POST-DOCS AND PRE-DOCTORAL STUDENTS CONDUCT RESEARCH ON THESE TOPICS

# 9

CSU PROPOSAL - CONTENT CONTINUED

1. COMBINING ENVIRONMENTAL DATA

FROM SURVEYS TO REMOTELY SENSED

POSSIBLY INCLUDING INFORMATION FROM “HAND-PICKED”SITES

2. LOCAL INFERENCE

3. AQUATIC INDICATORS

DEVELOPING DATA TO USE IN SPATIAL ANALYSES

LANDSCAPE ECOLOGY

REGIONAL TAXONOMIC RICHNESS

DAVE THEOBALD, NATURAL RESOURCES ECOLOGY LAB

URQUHART, RITTER (SCCWRP)

# 12

CSU PROPOSAL - CONTENT CONTINUED III

OUTREACH

“PROPOSALS SHOULD SPECIFICALLY ADDRESS THE EXTENSION OF EXPERTISE ON DESIGN AND ANALYSIS TO STATES AND TRIBES”

HARI IYER & NSU PREPARED THIS PART OF THE CSU RESPONSE

DAVIS, REICH,

JIM LOFTIS (BIORESOURCES ENGINEERING),

STEPHEN JOHNSON (WATER QUALITY TECHNOLOGY)

CSU PROPOSAL - CONTENT CONTINUED III

5. ADMINISTRATION

INTEGRATION AND COORDINATION

URQUHART & DAVIS

STEVENS (OSU)

AQUATIC SUPPORT: HERLIHY & HUGHES (OSU)

# 14

CSU PROPOSAL - FUNDED ACTIVITIES APPROXIMATE ANNUAL LEVELS

POST DOCTORAL FELLOWS

DOCTORAL STUDENTS

FACULTY TIME

OTHER 2.5

2 ~ 1 FTE (12M)

SUBCONTRACT TO OSU ~ $120K

COMPUTING EQUIPMENT - ONE TIME =$20K

SUPPORT/TRAVEL AMPLE

# 15

OSU COMPANION PROPOSAL

SIMILARILY STRUCTURED

MAJOR DIFFERENCE = FOCUS

DESIGN-BASED/MODEL ASSISTED

OSU SUBCONTRACT TO CSU THE SAME SCALE AS CSU SUBCONTRACT TO OSU

BOTH PROGRAMS HAVE OTHER SUBCONTRACTORS THE FIRST YEAR

# 16

WHAT IS DISTINCTIVE ABOUT’ “AQUATIC RESOURCES”?

THEY ARE THINGS LIKE

STREAMS

RIVERS

WETLANDS

LAKES & PONDS

ESTUARIES

PRAIRIE POTHOLES

NEAR COASTAL OCEANIC WATERS

# 17

WHAT IS DISTINCTIVE ABOUT’ “AQUATIC RESOURCES”?

CONTINUED

FOR MOST AQUATIC RESOURCES,

THERE ARE MANY “SMALL” ONES

PROGRESSIVELY FEWER AS THEY GET BIGGER

INTEREST, BIOLOGICAL & SOCIETAL, TENDS TO STAY CONSTANT OR EVEN INCREASE WITH SIZE

SIMPLE RANDOM SAMPLING WOULD SELECT MOSTLY “SMALL” ONES, FEW BIG ONES.

IMPLICATION:

UNEQUAL PROBABILITY SAMPLING

# 18

WHAT IS DISTINCTIVE ABOUT’ “AQUATIC RESOURCES”?

CONTINUED II

SPATIAL STATISTICS TENDS TO FOCUS ON TWO-DIMENSIONAL SPACE

STREAMS AND RIVERS ESSENTIALLY AMOUNT TO ONE-DIMENSIONAL OBJECTS IN TWO-SPACE

BUT MUCH LANDSCAPE INFORMATION IS COMPLETE COVERAGE IN TWO-SPACE

CHALLENGE:

MERGE THESE PERSPECTIVES

# 19

DISTINCTIVE EMAP PERSPECTIVE

DEFINE THE POPULATION OF INTEREST

CONDUCT A PROBABILITY SURVEY OF IT

CAREFULLY DEFINE THE SAMPLING FRAME

VARIABLE PROBABILITY SELECTION OF SITES, BUT WITH SPATIAL BALANCE

CAREFULLY DEFINE RESPONSES TO BE EVALUATED

TRAIN FIELD CREWS WELL

MANAGE DATA WITH CARE AND AN “AUDIT TRAIL”

LEARN FROM PAST MISTAKES, THROUGHOUT

SEE A FEW ILLUSTRATIONS

DATA SETS TO BE USED

# 20

AN EMAP STUDY: NORTHEAST LAKES SAMPLING MODEL - DISCRETE

TWO STEP SELECTION PROCESS

FIRST STEP = SPATIALLY SYSTEMATIC

EMAP = 1/64 EACH YEAR

FOUR YEARS ===> 1/16 AREA SAMPLE

SECOND STEP = PROBABILITY

INCLUSION PROB VARIED BY LAKE SIZE CLASS

SPATIAL RESTRICTION - MILD

CAN BE DESCRIBED FOR INTERESTED PEOPLE

TIME ESSENTIALLY THE SAME, EXCEPT AN ADDITIONAL 2/64 EXTRACTION WAS DONE

ONLY IN ITS AREAS OF INTEREST

SELECTING SITES - ILLUSTRATION

# 27

DISTINCTIVE EMAP PERSPECTIVE CONTINUED

IF DISCIPLINES LACK TOOLS, SUPPORT DEVELOPMENT OF THEM

STATISTICS INCLUDED

EXAMPLE: EXTEND CONCEPTS OF SAMPLING FROM FINITE POPULATION TO SPATIALLY CONTINUOUS POPULATIONS

NATIONAL RESEARCH CENTER FOR STATISTICS AND THE ENVIRONMENT (~ $1M/YEAR)

UNIVERSITY OF WASHINGTON PAST 5 YEARS NOW TO BE AT UNIVERSITY OF CHICAGO

TWO PROGRAMS UNDER DISCUSSION HERE

# 28

FUTURE NEEDS - STATES & TRIBES

STATES AND TRIBES MUST REPORT ON THE CONDITION OF ALL “WATERS” UNDER THEIR JURISTICTION

A REQUIREMENT OF SECTION 305b OF THE CLEAN WATER ACT

RESULTS IN BIANNUAL REPORT TO CONGRESS

STARTING IN 2004 NEW RECOMMENDED STANDARDS WILL REQUIRE THESE BE BASED ON PROBABILITY SAMPLING

# 29

FUTURE NEEDS - STATES & TRIBES CONTINUED

PROJECT # 4 WILL HELP

IDENTIFY NEEDED SKILLS IN THE STATES & TRIBES

DEVELOP THE NEEDED SKILLS

IF POSSIBLE, WE HOPE TO TRANSMIT THE LEARNING MATERIALS IN WEB-COMPATIBLE DOCUMENTS

RECORDED ON A CD ROM USABLE AT ANY REMOTE SITE
