I'm not going to recommend any gear, but I do recommend eyes. If you look around you, you will find beauty. For someone who lives in a desert, your land of trees would be mind-bogglingly beautiful. Try to see them through fresh eyes.It's more than just the subject matter in front of you that goes into an image. It is your vision. What moves you to take a photo in the first place? What moves you about what you are photographing? How do you capture that and convey it to others? You are not just taking pictures; you are making them.
It's easy to suffer from scenery envy; I know I have. But many of my favourite photographs have been taken in and around my home town of London, Ontario, not too far and probably not too different from your own part of the world. Certainly not exotic or spectacular to my mind, compared to other places, but, here I am. I make do. You can too! You can make compelling images wherever you are.
Take advantage of the changes of seasons you have where you live. Try going out in a variety of weather conditions (fog, mist, approaching storm, sunrise/sunset, etc.) Use your photographic skills. Your choice of angle of view, time of day, lighting, etc., all give you control of the viewer's attention. Look at colour, form, texture, light and shadow, pattern and rhythm. You can
make beauty with your selection and arrangement of these visual elements. You don't need exotic locales to find any of these things. You just need to find them for yourself. If you can't find anything "beautiful" around you to photograph, a new camera and lenses will not help you.
I do a lot of macro photography. Now that's a great way to see new things! I remember a day last year when I'd planned to go to a local pond to shoot insects. I never made it off my front porch! I encourage you to find the beauty right at hand. Not all that is beautiful is wildly spectacular: some beauty whispers. All you have to do is listen.
