BRIAN C. TEFFT, RHODE ISLAND DIVISION OF FISH AND WILDLIFE, P.O. BOX
218, WEST KINGSTON, RI02892, USA ABSTRACT THE APPALACHIAN COOPERATIVE
GROUSE RESEARCH PROJECT (ACGRP) WAS A MULTISTATE COOPERATIVE EFFORT
INITIATED IN 1996 TO INVESTIGATE THE APPARENT DECLINE OF RUFFED GROUSE
{BONASA UMBEL/US) AND IMPROVE MANAGEMENT THROUGHOUT THE CENTRAL AND
SOUTHERN APPALACHIAN REGION (I.E., PARTS OF OHIO, PENNSYLVANIA, RHODE
ISLAND, KENTUCKY, WEST VIRGINIA, VIRGINIA, AND NORTH CAROLINA, USA).
RESEARCHERS HAVE OFFERED SEVERAL HYPOTHESES TO EXPLAIN THE LOW ABUNDANCE
OF RUFFED GROUSE IN THE REGION, INCLUDING LOW AVAILABILITY OF
EARLY-SUCCESSIONAL FORESTS DUE TO CHANGES IN LAND USE, ADDITIVE HARVEST
MORTALITY, LOW PRODUCTIVITY AND RECRUITMENT, AND NUTRITIONAL STRESS. AS
PART OF THE ACGRP, WE INVESTIGATED RUFFED GROUSE POPULATION ECOLOGY. OUR
OBJECTIVES WERE TO ESTIMATE REPRODUCTIVE RATES, ESTIMATE SURVIVAL AND
CAUSE-SPECIFIC MORTALITY RATES, EXAMINE IF RUFFED GROUSE HARVEST IN THE
APPALACHIAN REGION IS COMPENSATORY, AND ESTIMATE RUFFED GROUSE FINITE
POPULATION GROWTH. WE TRAPPED 3,000 RUFFED GROUSE IN AUTUMN (SEP-NOV)
AND SPRING (FEB-MAR) FROM 1996 TO SEPTEMBER 2002 ON 12 STUDY AREAS. WE
DETERMINED THE AGE AND GENDER OF EACH BIRD AND FITTED THEM WITH
NECKLACE-STYLE RADIOTRANSMITTERS AND RELEASED THEM AT THE TRAP SITE. WE
TRACKED RUFFED GROUSE 2 TIMES PER WEEK USING HANDHELD RADIOTELEMETRY
EQUIPMENT AND GATHERED DATA ON REPRODUCTION, RECRUITMENT, SURVIVAL, AND
MORTALITY. RUFFED GROUSE POPULATION DYNAMICS IN THE APPALACHIAN REGION
DIFFERED FROM THE CENTRAL PORTION OF THE SPECIES RANGE (I.E., NORTHERN
UNITED STATES AND CANADA). RUFFED GROUSE IN THE APPALACHIAN REGION HAD
LOWER PRODUCTIVITY AND RECRUITMENT, BUT HIGHER SURVIVAL THAN REPORTED
FOR POPULATIONS IN THE GREAT LAKES REGION AND SOUTHERN CANADA.
POPULATION DYNAMICS DIFFERED BETWEEN OAK (QUERCUS SPP.)-HICKORY (CARYA
SPP.) AND MIXED-MESOPHYTIC FOREST ASSOCIATIONS WITHIN THE SOUTHERN AND
CENTRAL APPALACHIAN REGION. PRODUCTIVITY AND RECRUITMENT WERE LOWER IN
OAK*HICKORY FORESTS, BUT ADULT SURVIVAL WAS HIGHER THAN IN MIXED-
MESOPHYTIC FORESTS. FURTHERMORE, RUFFED GROUSE PRODUCTIVITY AND
RECRUITMENT WERE MORE STRONGLY RELATED TO HARD MAST (I.E., ACORN)
PRODUCTION IN OAK-HICKORY FORESTS THAN IN MIXED-MESOPHYTIC FORESTS. THE
LEADING CAUSE OF RUFFED GROUSE MORTALITY WAS AVIAN PREDATION (44% OF
KNOWN MORTALITIES). HARVEST MORTALITY ACCOUNTED FOR 12% OF ALL KNOWN
MORTALITIES AND APPEARED TO BE COMPENSATORY. POPULATION MODELS INDICATED
RUFFED GROUSE POPULATIONS IN THE APPALACHIAN REGION ARE DECLINING (X =
0.78-0.95), BUT DIFFERENCES IN MODEL ESTIMATES HIGHLIGHTED THE NEED FOR
IMPROVED UNDERSTANDING OF ANNUAL PRODUCTIVITY AND RECRUITMENT. WE POSIT
RUFFED GROUSE IN THE APPALACHIAN REGION EXHIBIT A DINAL POPULATION
STRUCTURE CHARACTERIZED BY CHANGES IN LIFE-HISTORY STRATEGIES. CHANGES
IN LIFE HISTORY STRATEGIES ARE IN RESPONSE TO GRADUAL CHANGES IN FOREST
STRUCTURE, QUALITY OF FOOD RESOURCES, SNOWFALL AND ACCUMULATION
PATTERNS, AND PREDATOR COMMUNITIES. MANAGEMENT EFFORTS SHOULD FOCUS ON
CREATING A MOSAIC OF FOREST STAND AGES ACROSS THE LANDSCAPE TO
INTERSPERSE HABITAT RESOURCES INCLUDING NESTING AND BROOD COVER, ADULT
ESCAPE COVER, ROOSTING SITES, AND, MOST IMPORTANTLY, FOOD RESOURCES.
LAND MANAGERS CAN INTERSPERSE HABITAT RESOURCES THROUGH A COMBINATION OF
DEARCUTTING, SHELTERWOOD HARVESTS, GROUP SELECTION, AND TIMBER STAND
IMPROVEMENT (INCLUDING VARIOUS THINNINGS AND PRESCRIBED FIRE). MANAGERS
SHOULD MAINTAIN CURRENT RUFFED GROUSE HARVEST RATES WHILE PROVIDING HIGH
QUALITY HUNTING OPPORTUNITIES. WE DEFINE HIGH QUALITY HUNTING AS LOW
HUNTING PRESSURE, LOW VEHIDE TRAFFIC, AND HIGH FLUSH RATES. MANAGERS CAN
PROVIDE HIGH QUALITY HUNTING OPPORTUNITIES THROUGH USE OF ROAD CLOSURES
IN CONJUNCTION WITH HABITAT MANAGEMENT. (WILDLIFE MONOGRAPHS 168, 1-36)
