Jeffery’s 28 Pushes Buffs To Pac-12 Win
Jan 9th
BOULDER – Linda Lappe’s third Colorado women’s basketball team is more balanced than her first two, but after a pair of Pac-12 Conference losses she wisely recognized that a stronger dose of Chucky Jeffery might be just as beneficial as balance.
After dropping consecutive home games to No. 4 Stanford and No. 7 California, Lappe and Jeffery talked – and on Tuesday night Jeffery responded. The senior point guard scored a season-high 28 points and collected 12 rebounds to lead No. 23 CU to its first Pac-12 win of the season, 67-57 over Utah at the Coors Events Center.
“Chucky came out a lot more aggressive,” Lappe said. “She was tentative against Cal and Stanford . . . we needed more from her.”
More is what Jeffery delivered, helping key a 20-3 second-half run as the Buffaloes (12-2, 1-2) finally pulled away from the uncooperative Utes (9-5, 0-3).
CU also was lights out from the free throw line, hitting 22 of 26 in the second half and 23 of 28 for the game. The Buffs’ final nine points came from the foul line, and they sealed the win by sinking five of six free throws in the final 33 seconds.
Lappe said Jeffery, whose 10 field goals tied a season high, “got in a great flow offensively . . . she took her time, but she was being aggressive and everything was in rhythm. She didn’t force too much.”
Registering her 23rd career double-double (third this season), it was the type of trademark performance expected of Jeffery in her first three CU seasons. “And we still need that from her,” Lappe said. “She knew when we needed to score . . . she understood her role and sometimes that’s taking the bull by the horns. There are times when we need her to step up; she understands big possessions.”
It wasn’t as if Jeffery was completely unproductive against Stanford (17 points) and Cal (13). But she agreed with her coach about playing tentative to open Pac-12 play: “After the past two games, I watched film with coach . . . and I was tentative and wasn’t looking to score. She just wanted me to be more aggressive. She told me when I’m more aggressive I make smarter and better decisions to create and help my teammates score as well.”
CU won’t have to put in extensive film study for its next game with Utah. The Buffs play the Utes in Salt Lake City on Sunday (3 p.m.). Last season, CU and Utah split their regular-season series, with each team winning on the road and CU breaking the tie with a win in the Pac-12 tournament.
The Buffs only led once in Tuesday’s first half, and it took them 19 minutes to finally catch the Utes. They did it by closing the half on a 10-1 run, with eight of the points scored by Jeffery as CU took a 32-31 lead at intermission.
Behind Plouffe’s 11 first-half points, Utah led by eight points on two occasions before CU shook itself awake. The Utes’ last eight-point advantage (30-22) came on a pair of Wicijowski free throws with 4:42 remaining before the break.
That’s when Jeffery went to work, getting eight of her 14 first-half points in the final 41/2 minutes. The Buffs’ other basket was scored by freshman Jamee Swan, who finished with a career-high 11 boards and eight points in 22 minutes and was a catalyst in CU catching up in the first half, said Lappe: “She kept us in the game for a lot of the first half.”
The Buffs’ 32 first-half points gave them a nice start toward finally reaching 50 in their third conference home game. They managed only 40 and 49 in the two previous losses, marking the first time since the 1974-75 season CU had been held under 50 points in consecutive home games.
But that wasn’t a second-half focal point for the Buffs; scoring 49 and getting a one-point win would have been fine. They opened the second half with a basket by Swan, taking their largest lead (34-31) of the night to that point.
Plouffe answered for Utah (34-33), then got a trey by Rachel Messer to go up 36-34. Meagan Malcolm-Peck’s layup tied the score at 36-36 before a 9-2 Utes run opened a 45-38 advantage for the visitors with just under 13 minutes to play.
It was the Buffs’ turn to respond, and they did with an 11-1 run, with seven of the points made at the free throw line. The final pair by Brittany Wilson put CU up 49-46 with 8:49 left.
Jeffery took it from there. After hitting a short jumper, she got a steal at the other end, was fouled and hit two free throws for a 55-48 Buffs lead. And when the Utes misfired on their next possession, Jeffery made them pay with a three-pointer from the top of the key that completed CU’s 20-3 surge and opened a 10-point lead (58-48) with 5:58 remaining.
The Utes pulled to within five points (62-57) when Plouffe made one of three free throws with 36.1 seconds to play. But the Buffs pulled away at the free throw line, hitting five of six free throws to pocket their first Pac-12 win.
“I’m happy . . . it’s nice to get that first one,” Lappe said. “You have to give Utah credit, though; they don’t beat themselves. You really have to work hard to beat Utah.”
A chance for a sweep comes again in five days, which Lappe calls “different (because) we play them again so soon . . . I think there will be some changes by both teams, but for the most part we know each other’s game.”
The Utes know Jeffery’s game, said Utah coach Anthony Levrets: “We played a really good team and obviously Chucky made a ton of plays to beat us. But I’m pleased with my team’s effort and we’ll keep working and try to get ourselves ready to go on Sunday.”

BEETLE KILL LIKELY TO WORSEN HIGH RUNOFF
Jun 8th
ACCUMULATION AND MELT, SAYS CU-BOULDER STUDY
A new University of Colorado Boulder study indicates the infestation of trees by mountain pine beetles in the high country across the West could potentially trigger earlier snowmelt and increase water yields from snowpack that accumulates beneath affected trees.
Led by CU-Boulder geological sciences department doctoral student Evan Pugh, the study was undertaken near Grand Lake, Colo., adjacent to Rocky Mountain National Park, an area that has been devastated by mountain pine beetle attacks in recent years. Mountain pine beetles have killed more than 4 million acres of lodgepole pine trees in Colorado and southern Wyoming since 1996, the most severe outbreak on record.
Pugh and his team monitored eight pairs of tree stands, each pair consisting of one live stand and one dead stand roughly an acre each in size and located adjacent to each other, sharing the same topography, elevation and slope. The team monitored the two distinct phases of pine beetle tree death during the three-year study — the “red phase” in which dead trees still retained red needles, and the “gray phase” in which all of the tree needles and some small branches had been shed, said Pugh.
The study showed that there was roughly 15 percent more snow accumulation under the gray phase stands than under living stands or red phase stands, likely due in large part to a lack of “snow interception” by needled tree branches that can cause snowflakes to “sublimate” into gas and return to the atmosphere, he said. Gray phase trees also allow more solar radiation through their canopies than live trees and red phase trees, increasing the potential for earlier melt, said Pugh, lead study author.
Snowmelt rates were highest under red phase trees, with snow disappearing up to a week earlier than snow in adjacent, healthy stands even though both received the same amount of snowfall at their bases. Pugh showed the earlier snowmelt in red phase tree stands is due in large part to the amount of litter — needles and branches — that drops or is blown from the trees onto on the snow surface, decreasing its solar reflecting power, or albedo, and causing it to absorb more of the sun’s radiation and heat up slightly.
“This is the first study to look at the potential effects that different stages of mountain pine beetle tree death may have on snowmelt,” Pugh said. “What we are seeing is earlier snowmelt and more snow accumulation in dead forests.”
A paper on the subject was published online today in the peer-reviewed journal, Ecohydrology. The paper was co-authored by CU-Boulder geological sciences Professor Eric Small and funded in part by a CU-Boulder Innovative Seed Grant. Four undergraduates — Leslie Baehr, Tevis Blom, Bryant Kealey and Jon Hammond — received internship credit for helping to conduct the research.
The study took place at the headwaters of the Colorado River in north-central Colorado. Six of the eight healthy tree stands in the study were made up primarily of lodgepole pines, while two were made up of mixed conifer trees. “One of the hardest parts of this study was to find stands of healthy trees in this area,” said Pugh.
The red phase that occurs following tree death usually lasts about 18 months, and the onset of the gray phase occurs about three or four years after tree death, said Pugh.
“One of the big surprises to me was that changes in snowpack depth and snowmelt timing as a result of the pine beetle outbreak were not larger,” said Small. But the continuing effects could become more significant in the coming decades, he said.
The CU-Boulder team used a wide variety of instruments during the study. In addition to avalanche poles used to periodically measure the snow depth at the 16 study stands, the team also inserted tiny thermometers at various snow depths to help them predict when the snow would likely melt. They also dug snow pits in each of the tree stands and weighed known volumes of snow to calculate density and water content.
Pugh’s team also used devices known as pyranometers to measure the snow surface albedo and the transmission of sunlight through forest canopies. Fisheye camera images taken from the snow surface helped the researchers to calculate the size and structure of the various tree stand canopies, he said.
“The students really got something out of working on this project,” said Small. “Not only did they get internship credit, they had a chance to conduct meaningful research.”
A massive fire in the study area in the late 1800s resulted in most of the succeeding lodgepole pines to be about the same size and age, making them easier targets for pine beetles. While mountain pine beetle infestations are natural events, climate change probably has played a role in the most recent outbreak. Drought conditions in the West in recent years have caused living pines to absorb less water, decreasing their ability to produce enough sap to “pitch out” beetles that are attacking them, Pugh said.
Water managers in Salt Lake City have reported extra water in river basins that hydrologic models had not predicted, Pugh said, an indication beetle-killed trees are having an impact on meltwater.
With the exception of two studies in British Columbia looking at the effects of beetle- killed lodgepole pine trees on snow accumulation and melt on flat terrain at a single site, research regarding the hydrologic impacts of mountain pine beetles has largely been speculative, said Pugh.
“Our study is the first to analyze the multiple stages of tree death from mountain pine beetles and their different impacts on snow accumulation and snowmelt,” said Pugh. “There is no on/off switch here — only gradual changes.
“The effects of the beetle-killed tree stands in terms of snow accumulation are not going to affect ski resort seasons by any means,” he said. “What we can say is there likely will be additional water resources for water managers. Additional snowpack coupled with dead trees that are no longer sucking up water will likely lead to more runoff.”
