Today (Sunday 04/22/2018), I monitored our group's five Multiflora rose (Rosa multiflora) shrubs at the Radford Bike Path site in Radford, Virginia. Throughout the week, we have seen mostly sunny skies and fluctuating average temperatures ranging from the low 60s to the upper 70s. Today was partly cloudy with a light breeze and a high of 65 and a low of 55. All five plants showed small amounts of breaking leaf buds (around 3-10) however most leaves have grown to around 75%-95% of their full potential size. Almost all of the shrubs are filling around 95% of their total canopy cover, however there's still no sign of emerging flower buds. Only one bush was bearing any noticeable fruit. Four out of our five plants were recently crushed by fallen branches during a snow store. Out of the two bushes we had observed bearing ripe fruit, only one was left with any fruit as the damage knocked it all off of the other plant. (Post by T. Thompson)

Today (Friday 4/15/2018), I observed our specimens of Multiflora rose (Rosa multiflora) shrubs at the Radford Bike Path site in Radford, Virginia. The weather has been warm and sunny this week with highs in the upper 70's. The three shrubs that endured little damage from previous weeks are showing >95% canopy cover and the majority of their leaves are at 75-94% of their full size. Breaking leaf buds occurred in all five shrubs. This may be due to the cold snap we had last week followed by seasonally warm temperatures. (Post by C. Gleason)
Today (Friday 4/6/2018), I observed our specimens of Multiflora rose (Rosa multiflora) shrubs at the Radford Bike Path site in Radford, Virginia. The weather this past week has been mild and rainy with an average rainfall at 0.27in and an average temperature of 62 degrees Fahrenheit. Today during my monitoring, it was partly cloudy with temperatures in the mid 60’s. The shrubs are currently enjoying the rain and warmer temperatures compared to the snow that has recently damaged some of them. The plants are practically finished with the breaking leaf bud stage, though the majority still show 3-10 breaking leaf buds, some had 11-100 on the plants where less light was available. All but one of the shrubs have reached about 50-74% of potential leaf size. Plants all have about 50%-74% of the total potential canopy space filled with leaves. (Post by Z. Underwood)
Today (Thursday 3/30/2018), I monitored our group's five Multiflora rose (Rosa multiflora) shrubs at the Radford Bike Path site in Radford, Virginia. The weather has been varied this week from snowing 8 inches to being sunny and warm. Today it was partly cloudy with temperatures in the mid 70’s. Due to the heavy snowfall earlier in the week, some of our shrub bushes have damaged by fallen branches. The snow also appeared to knock down the remaining fruit on one of the multiflora rose shrubs. Most of the plants are almost finished with the breaking leaf bud stage, with some still having 3-10 breaking leaf buds on the plant. It appears that the plants have reached about 50-74% of leaf size and we expect to see them at full size in the next few weeks. Plants continue to cover about 50%-74% of the total potential canopy space. (Post by M.

Throughout the week, we have seen partly cloudy skies with a few days of snow accumulation up to 3 inches. Today it was overcast with a steady fall of snow expected to reach 8 inches. The high temperature today is 40° F and low is 30° F with snow expected to fall all day. It appears that some plants have begun to have higher numbers of breaking leaf buds again while others had very few if any. While more leaves have emerged on all the bushes, the majority of them were still small and increasing in size. In most of the shrubs, the leaves are approximately 50%-74% of the size they will be when fully grown. Plants are beginning to cover 50%-74% of the total potential canopy space. Two of our shrubs continue to bear fruit. (Post by M.

The weather was cool (43° F) with clear skies. Earlier in the week we got approximately 4 inches of snow. Warmer temperatures through the week melted most of the snow that had accumulated. Three of our shrubs have seen a slight decrease in breaking leaf buds compared to last week. The only other noticeable changes this week is that two of our shrubs have filled more of their canopy space compared to the weeks prior (now, 50-74%). These changes are most likely the results of former "breaking leaf buds" developing into leaves that have begun growing in attempt to reach their full size. (Post by D. Hardware).
Today (Saturday 03/10/2018), I monitored our group's five Multiflora rose (Rosa multiflora) shrubs at the Radford Bike Path site in Radford, Virginia. Throughout the week, we have seen mostly gray skies and even some scattered snow flurries with temperatures ranging from the low 30s to low 50s with a forecast of snow, up to 6 inches, later on in the week. Today was overcast and cool with a high of 51 and a low of 35. Compared to last week, all 5 plants had a fewer number of breaking leaf buds, as most leaves have unfolded to expose visible leaf stalks. While more leaves have emerged on all the bushes, the majority of them were still small and increasing in size being, in most cases, approximately 25%-49% of the size they will be when fully grown. Because of this, most bushes still have leaves only covering around 25%-49% of total potential canopy space with the exception of one who's leaves are small but are appearing in bigger clusters than the others (covering approximately 50%-74% of total canopy space). Two of the five plants were bearing ripe fruit, however the fruits appeared to be more withered than they were during last weeks monitoring. (Post by T. Thompson)
On Saturday March 3rd, 2018, I monitored our team's five multiflora rose (Rosa multiflora) shrubs at our Radford Bike Path site in Radford, Virginia. It was a sunny, but cool windy day reaching a high of around 50°F. This week we've seen temperatures much lower than last week and have had a few very windy days. Since the previous monitoring, I noticed a significantly higher number of leaves on each bush. Leaves were covering approximately 25% or more of total canopy space on most plants observed. The majority of leaves present on all five plants have not reached their full size and are roughly 25% of the size they will be when fully grown. Two of the five plants bear small clusters of ripe fruit. (Post by T.

As with last week, temperatures have continued to be higher than normal with temperatures exceeding 80°F. Since last weeks monitoring there has been only slight changes to each of the five plants. Each shrub has seen a slight increase in the number of breaking leaf buds but are still within the same window as last week (101-1,000). Few leaves (>5% Total Canopy) were seen on all five plants. Of the leaves present, most are continuing to increasing in size, and on average they are at 25% of their potential size. As with last week, two of our plants continue to bear ripe fruit. (Post by T.

On February 18, 2018, I monitored our team's five multiflora rose (Rosa multiflora) shrubs at our Radford Bike Path site in Radford, Virginia. It was a warm, sunny day (55°F) following an unusually warm week where temperatures rose above 65°F and rain persisted much of the week. Since last weeks monitoring, I have notice that many of the understory plants are beginning to leaf out and develop some color. On the multiflora rose shrubs, I noticed that the leaves have a red outline at the end of each leaflet. On all five of our shrubs, I estimated more than 100 breaking leaf buds on each shrub. Additionally, two of our shrubs were bearing ripe fruit that was not present the week prior. When ripe, the fruit are red, fleshy, and about the size of a pea. (Post by C Gleason.)
On February 8, 2016, we hiked down to the a strip of forest edge habitat alongside the New River and Radford Bike Path in Radford, Virginia. It was a cool, sunny day (42°F). Our team choose five different Multiflora Rose (Rosa multiflora) shrubs to study over the course of the semester. Once each team member had chosen a shrub, we attached to each rose bush both a marked piece of pink ribbon and a metal tag providing the identity of each individual shrub. On all five bushes, we noticed leaves that appeared to still be growing in size (<25% of full size). On one of our shrubs in a particularly shady spot had no breaking leaf buds compared to the other four shrubs that had few breaking leaf buds (3-10). Leaf buds are considered "breaking" when the green tip of the leaf is visible at the end of the bud. Across all shrubs we still don't have any evidence of flower buds, open flowers, or fruit.
