Many of the inhabitants fear a spread of the war from eastern Ukraine.
Geography gives their region great strategic importance, especially if the Russians were ever tempted to try to carve a land corridor across to Crimea, Odessa and the Romanian border.
Ukrainian Bessarabia is bounded by the Black Sea, the Danube and Moldova.
The Russian-controlled breakaway region of Transdniestria is to the north.
There are no roads, bridges or ferries across the Danube to Romania and only two roads connect the region to the rest of Ukraine.
If the bridges over the Dniester were blown up, it would be cut off.
Fewer than half of the region’s 570,000 people are Ukrainian.
The rest are Bulgarians, Russians, Moldovans, Gagauz or Albanians.
Many have a benign view of Russia, which gave their ancestors land and freedom 200 years ago.
Almost everyone speaks Russian and many complain that Ukraine has done little for them.
Ivan Rusev, a local ecologist, tracks illegal buildings in the Dniester Delta National Park.
This was a problem before Ukraine’s 2014 revolution, he says, but it is worse now.
The result is a contradiction.
For pro-Ukrainians such as Mr Rusev, too many fellow Bessarabians hope vaguely that “Putin will solve all their problems.”
Few have any faith in the government in Kiev.
Yet according to Anton Kisse, a local politician, at the same time as many feel sympathy for Russia, they also favour Ukraine’s unity.
Sergey Dibrov, a journalist in Odessa, believes that, given the region’s ethnic make-up, any declaration of independence would see the region splinter into bits.
In the autumn there were rumours of plots to proclaim a pro-Russian Bessarabian People’s Republic, along the lines of the separatist republics in Ukraine’s Donbas region.
Possible leaders included former Soviet army officers living in Bolgrad, which is mostly ethnic Bulgarian.
Yet war in the east has dampened enthusiasm for separatism.
A tragedy last May which saw dozens of pro-Russian activists killed in a fire in Odessa has also chilled any desire for revolt against Kiev.
Pro-Russian leaders have fled and opportunistic politicians have shifted towards supporting the unity of Ukraine.
The question is what Russia wants.
State power has changed hands nine times in Bessarabia in just over 200 years.
Locals report seeing drones, some perhaps from Transdniestria and some that may have come from ships of Russia’s Black Sea fleet, based in Sebastopol.
Even so, Ukraine’s flag looks likely to fly over Bessarabia for some time to come.
