Field Notes
Lonicera Morrowii Morrow’s Honeysuckle The main purpose for me was to find out if there is any invasive honeysuckle (Morrow’s Honeysuckle) living in or around my area. I did this to help scientist study and track invasive species in Maine. My sampling method was just walking around outside and down my road, taking pictures of the area, and what it looks like. I found that the population of honeysuckle this time of year, is huge, and easy to spot. I found the honeysuckle in a yard, next to a field, with a large group of them all lined up together, all the way to the road. I would say that the habitat it’s living in is fairly developed, with roads and housing near by, but still where trees, and water are very close. Date: May 15th 2012 Time: 3:30pm Temperature: 19˚c Humidity: 71% Sunlight: Partly Cloudy Soil Moisture: Little, mostly dry Other: little wind, sunny the day before I noticed a large amount of bees, as many as 3 or 4 per bush, many other small insects crawling on the leaves; flies, small beetles, and some spiders. The bushes ranged dramatically in height, some bushes were 1.5-2 meters tall, others were only as high as 60 centimeters. They seemed to grow closer to trees then by themselves, mostly close to the sides of trees, and some of the branches intertwining. They had few plants growing under them. Their biotic potential must be high, because honeysuckle was everywhere, I saw bees on the bushes, so their seeds must get around easily, and with so many flowers, there must be many seeds. I don’t think they have many limiting factors, they block out the sunlight for other native plants to grow underneath, so they don’t have much competition, and they are in thick rows, very close to each other. I’m assuming they have organisms that eat them because I saw holes in the leaes, and many bugs on the plant. They had green oval leaves, the sides were slightly wavy, but not drastically. The leaves were arranged opposite of each other, with one leaf on the end of each branch. Some of the branches seemed to wrap around the other in full loops. The branches were tan/brown, and the newer (or what appeared to be newer) had small fuzz on them. The leaves had small white fuzz on the underside. The flowers ranged in color from very pale green, to white, to cream. All of the bushes were in full bloom, and the flowers were in pairs on each stem. The flowers had long, thin, slightly curled, spread out petals. The leaves were 4-6 cm long, and the tallest bushes were 2 meters high. It had a round stem with many branches throughout.

Supporting Evidence
Photo of my evidence.
There are pale white/cream colored flowers all over the bushes.

The plant has oval leaves, and the underside of the leaves are fuzzy, very fine, but you can feel them.

The bushes are a complex, twisting amount of branches, wrapped around each other, and difficult to see/ get to the root stem.

Nice work. Your field notes are well detailed and tell the whole story. I noticed that others have avoided the sketch as part of their submissions. Maybe you could be a sketcher for hire. You have some artistic talent for sure.

Your observation of lots of flowers/lots of seeds may well pan out. I'm anxious to see the sketch. Do you think an invasive plant is competing for space with another invasive plant?

I also just noticed that it looks like there might be some oriental bittersweet in the area. Did you notice that stuff that is in your sampling method photo? When you go back check it out. Let me know what you find.


That sketch is phenomenal! I can't wait to see the updated one with berries!

Thank yo fort eh compliment on the sketch, and thank you for the suggestion for oriental bittersweet in the area, I will check that out sometime.

I plan to go out sometime again in the fall, when the flowers turn into berries, then I will comment, with and up-dated sketch of the berries :)
