Spend time using your senses to make and record observations of the natural world. From those observations, begin to think about the questions you have about the world around you.
I have chosen my backyard for my field journaling. I have an herb garden that I started quite a few years ago. Herbs include lemon balm, lavender, sage, rosemary, thyme and a variety of mints. As time went on I added some strawberries. Along the north and east edges of the garden along the fence I planted morning glories. For about five years the morning glories would grow along the fence and were quite beautiful purples and lavenders. The herbs and strawberries flourished. But, for the past three years I have not tended the garden and things started happening. I now have a "mock" morning glory that strangles the other plants (it is not just in my herb garden either it is also invading my raspberry patch, currents, and gooseberries.
I really would like to know what this plant is. Is it native or an invader? How do I deal with it? What other plants have invaded my garden over the past three years? I no longer have the morning glories which would return every year. My strawberries and herbs are competing with other unknown species. What are these unknowns? I know that most of my problem is due to neglect but now I have quite a nice little "field site".
An interesting field site indeed. Sounds like a perfect place to make some VS observations.
